About Gas Valves

Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow. Connection types consist of bolt flanges, clamp flanges, union connections, tube fittings, butt welds, socket welds, and internal or external threads. Gas valves are used in a variety of applications and industries. For example, some devices are used in aerospace, agricultural, automotive, commercial, construction, cryogenic, fire service, food service, or flood control applications. Others are used in the food processing, irrigation, maritime, medical, mining, or semiconductor industries. High-purity gas valves are used to handle gases such as nitrogen, argon, oxygen, and hydrogen. Specialized gas valves are also used in oil and gas production, the pulp and paper industry, and power generation.

Products & Services Related to Gas Valves

Air Pressure Regulators

Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices.

Air Valves

Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.

Control Valves

Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system.

Diaphragm Valves

Diaphragm valves close by means of a flexible diaphragm attached to a compressor.

Plastic Valves

Plastic valves are made from plastic materials and are used in applications that require corrosion resistance and/or chemical handling.

Plug Valves

Quarter-turn plug valves use a cylindrical or tapered plug with a hole in the center to control straight through flow when in the open position.

Sanitary Valves

Sanitary valves are designed for applications requiring clean or sterile processing.
