What Al Muftah Supplies - Industrial Gas Valves for Low and High Pressure Gas Service, Engineered for Airgas, LNG, and LCO2
Al Muftah International supplies industrial gas valves in two distinct pressure configurations, each engineered for the specific demands of its service range. The low pressure series handles working pressures to 35 Kg/cm²g with flow capacities up to 5,000 Nm³/Hr in a single module — covering bulk gas distribution, process vaporisation, and utility gas header applications where high flow at moderate pressure is the dominant requirement. The high pressure series handles working pressures to 200 Kg/cm²g with flow capacities to 500 Nm³/Hr in a single module — for cylinder manifold supply, high-pressure gas injection, and compressed gas distribution where pressure rating is the primary selection driver.
Both series cover Airgas, LNG, and LCO₂ service — the three gas types that account for the largest proportion of industrial gas valve requirements across oil and gas, petrochemical, desalination, and general industrial applications in the GCC. Al Muftah supplies these valves as part of a complete gas infrastructure offering that includes cryogenic storage tanks, vaporisers, pressure reducing stations, and gas control systems — a single-source supply relationship for the entire gas handling system, not just the valve.
Low Pressure - 35 Kg/cm²g MAWP
LP series industrial gas valves rated to 35 Kg/cm²g maximum allowable working pressure — covering bulk gas distribution, vaporised gas headers, and utility gas supply for Airgas, LNG, and LCO2 service at high flow rates up to 5,000 Nm³/Hr.
High Pressure - 200 Kg/cm²g MAWP
HP series industrial gas valves rated to 200 Kg/cm²g MAWP — covering compressed gas cylinder manifold supply, high-pressure gas injection, and compressed Airgas and LNG distribution at elevated working pressures up to 500 Nm³/Hr.
Airgas, LNG, and LCO2 Service
Both LP and HP valve series are engineered for Airgas (nitrogen, oxygen, argon, air), LNG (liquefied natural gas), and LCO2 (liquid carbon dioxide) service — covering the materials compatibility, temperature range, and sealing requirements of all three gas types.
Single-Source Gas System Supply
Al Muftah supplies industrial gas valves alongside cryogenic storage tanks, vaporizers, pressure reducing stations, and gas control systems — one supplier for the complete gas handling infrastructure, eliminating the interface complexity of multi-vendor system assembly.
Who Al Muftah Supplies Industrial Gas Valves To
Industrial Gas Valves for Oil & Gas - LNG, Airgas, and Process Gas at Low and High Pressure
Offshore oil and gas platforms and FPSOs use Airgas industrial valves extensively across instrument air distribution, nitrogen utility headers, and compressed gas cylinder manifold supply systems. The HP series at 200 Kg/cm²g MAWP covers the cylinder manifold pressure range for nitrogen injection and instrument air supply. The LP series at 35 Kg/cm²g MAWP covers the downstream distribution headers where vaporised or decompressed gas is distributed to instrument and utility users at moderate working pressure.
Al Muftah's EPC background means valve supply for offshore projects comes with operator technical standard compliance, area classification documentation, and third-party inspection coordination that major operator procurement processes require.
What makes an oil & gas buyer choose Al Muftah industrial gas valves
- LNG-compatible materials - both LP and HP series specified for low-temperature LNG service conditions
- Full pressure span covered - HP series for cylinder manifold, LP series for distribution header, one supplier for both
- Offshore instrument gas supply - HP series at 200 Kg/cm²g covers nitrogen and instrument air cylinder manifold pressure range
Industrial Gas Valves for Desalination and Utility Applications - CO2, Airgas, and Instrument Gas Service
Power plants — gas turbine, combined cycle, and cogeneration — use industrial gas valves across fuel gas distribution, instrument air headers, hydrogen seal gas systems, and CO₂ fire suppression pre-action systems. Fuel gas distribution headers at turbine inlet conditions typically operate within the LP series 35 Kg/cm²g range. Instrument air at compressor outlet pressure and compressed gas cylinder supply for portable applications fall within both LP and HP series range, depending on the specific operating pressure of each service.
What makes a desalination and utility buyer choose Al Muftah industrial gas valves
- Water quality compliance - CO2 valve specification for remineralisation service with tight shutoff for pH-critical applications
- Fire suppression pre-action - CO2 valve specification for fire suppression system service included in LP series range
Industrial Gas Valves for Gas Distribution and Storage Facilities - Cylinder Filling, Bulk Storage, and Distribution Headers
Bulk liquid gas storage facilities — LNG satellite stations, liquid nitrogen storage for industrial supply, and liquid CO₂ storage for food and industrial distribution — use industrial gas valves at multiple points across the storage and vaporisation system. The LP series at 35 Kg/cm²g and up to 5,000 Nm³/Hr covers the high-flow vaporiser outlet and distribution header applications for LNG and LCO₂ satellite stations, while the HP series covers any high-pressure fill or injection points in the system.
What makes an industrial gas operation choose Al Muftah valves
- Cylinder filling pressure covered - HP series at 200 Kg/cm²g matches standard high-pressure cylinder fill pressure range
- High-flow distribution headers - LP series 5,000 Nm³/Hr single-module for LNG and LCO2 satellite station send-out headers
Six Requirements Every Industrial Gas Valve Selection Must Meet
From a gas distribution depot in Dubai to a petrochemical complex in Jubail — these six requirements define what an industrial gas valve specification must address. Al Muftah's LP and HP series meet all six.
Correct Pressure Rating
LP or HP – matched to service MAWP
The most basic industrial gas valve selection requirement: the valve's MAWP must exceed the maximum operating pressure of the service. LP series at 35 Kg/cm²g for bulk distribution and utility headers; HP series at 200 Kg/cm²g for cylinder manifold and high-pressure supply. Al Muftah advises on the correct series for each service point.
Flow Capacity to Match Demand
Up to 5,000 Nm³/Hr single module (LP)
A valve that is correctly pressure-rated but undersized for the flow requirement creates a process bottleneck. LP series single-module capacity to 5,000 Nm³/Hr covers the bulk of industrial gas distribution header flow requirements without parallel module arrangements.
Gas Service Compatibility
Airgas · LNG · LCO2 – materials specified
The valve's materials specification must be compatible with the gas service — including temperature, corrosivity, and sealing requirements. Both LP and HP series are specified for Airgas, LNG, and LCO2 service, with LP series additionally covering LCO2 and HP series covering high-pressure LNG applications.
Technical Specification Support
Series selection advice included
Valve selection requires engineering judgement — not just a catalogue. Al Muftah's technical team provides LP vs HP series selection advice for each service condition, including pressure, flow, gas type, and installation environment, before any procurement commitment is made.
Single-Source Gas System Supply
Valves and gas infrastructure together
Al Muftah supplies industrial gas valves alongside cryogenic storage tanks, vaporizers, pressure reducing stations, and gas control systems — one supplier for the complete gas handling infrastructure, eliminating the multi-vendor coordination risk of sourcing each component from a different contractor.
GCC Project Documentation
EPC and O&M supply both covered
Al Muftah supplies industrial gas valves for new EPC projects and for ongoing O&M replacement — with the technical documentation, material certificates, and project coordination required by GCC operator procurement standards and major EPC contractor quality management frameworks.
Frequently Asked Questions: Industrial Gas Valves from Al Muftah International
What is the difference between the LP and HP series industrial gas valves?
The LP series low pressure industrial gas valve is rated to 35 Kg/cm²g MAWP with a maximum single-module flow of 5,000 Nm³/Hr, covering Airgas, LNG, and LCO2 service. The HP series high pressure industrial gas valve is rated to 200 Kg/cm²g MAWP with a maximum single-module flow of 500 Nm³/Hr, covering Airgas and LNG service. The LP series is selected for high-flow distribution headers at moderate working pressure; the HP series is selected for cylinder manifold supply and high-pressure gas injection applications where working pressure exceeds the LP series rating.
Which Al Muftah valve series is correct for LCO2 service?
The LP series industrial gas valve is specified for LCO2 service — covering liquid CO2 distribution headers, CO2 post-treatment remineralisation supply in desalination plants, CO2 food processing distribution, and CO2 fire suppression pre-action systems at the 35 Kg/cm²g MAWP and up to 5,000 Nm³/Hr single-module flow that covers the majority of LCO2 distribution applications. Al Muftah's technical team advises on the specific material and seal specification for LCO2 service to address CO2 phase behaviour and hydrate formation requirements.
Can Al Muftah supply industrial gas valves for LNG terminal and FSRU applications?
