pneumatic safety valve for sale

We are a leading manufacturer of high quality valves serving the compressed air, pressure washer, automotive, fluid power, fire protection, specialty gas, and pneumatic industries.

The Model “ST” safety valve is our standard safety valve for small air compressor systems and related applications. Even though the size is compact, flow capacities are high.

Resilient rubber pad, offered in silicone or flourocarbon, insures valve is bubble-tight to within 10% of set pressure. Three inlet sizes are available: 1/8″ NPT, 1/4″ NPT, and 3/8″ NPT.

Model “SV” ASME safety valves are designed for systems where large flow capacities are needed. Resilient pad insures valve is bubble-tight to within 10% of set pressure. Inlet size: 1/2″ NPT.

Model “SB” safety valves offer Control Devices value to users of high capacity ASME safety valves. Unique O-ring seal insures valve is bubble-tight to within 10% of set pressure. 1/2″ NPT and 3/4″ NPT inlets available.

The model “SW” valve is our highest capacity ASME safety valve. Unique O-ring seal insures valve is bubble-tight to within 10% of set pressure. 1″ NPT and 1¼” NPT inlets available.

The Super-Chek® design has been proven over the last 15 years to be the standard for air compressor in-tank check valves. One-piece brass bodies, stainless steel springs, and glass-filled fluoropolymer poppets all add up to long term reliability, while the eight discharge holes insure quiet operation.

Valves may be disassembled for cleaning or repair. Valves are 100% tested for backflow leakage performance. 450 PSI max pressure, 400 deg. F max temperature.

These cast-brass check valves have been specifically designed for installation into air compressor discharge lines. Extra-heavy walled cast brass bodies, glass-filled fluoropolymer poppets, and stainless springs resist corrosion and insure long life.

Pneumatic pressure relief valves are fittings used to control air within a compressed air system. They are implemented within systems to prevent spikes in pressure which could cause damage to equipment. Pressure relief valves are designed to provide safety and to help the system maintain optimal performance.

Pneumatic pressure relief valves are set to a specific level of pressure. If this pressure is exceeded, the releases the excess pressure. The excess is released into the atmosphere when the valve opens.

Pressure relief valves can be installed throughout a pneumatic system, wherever protection is needed from potential spikes in pressure. They are often attached to a pipe, filter or a vale and feature a threaded port for attaching. Pressure relief valves are very easy to install.

The valves are usually made from a metal, such as stainless steel or brass. They often feature a seal to provide an air-tight fitting, which is usually made from plastic of rubber.

Many pneumatic systems require relief valves, for example compressors and process control systems. Some valves are designed for high pressure or high temperature environments too.

Industry leading pressure and safety relief valve designs with over 140 years of technical and application expertise providing custom engineered solutions for O&G, Refining, Chemical, Petrochemical, Process and Power applications. Our designs meet global and local codes and standards (API 526; ASME Section I, IV & VIII; EN ISO 4126; PED & more).

After trying a few of these from an order last year, we have been noticing they like to relieve pressure before the pressure switch for FRC pneumatic systems turns off. This means that whenever the system gets close to 120-125psi the RV will open and then the system drops do 110psi and continues to fill.
