Control Devices, Inc. Manufactures Quality Valves

In-Tank Check Valves

Super-Chek®

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.

Model "B2"

The "B2" design of in-tank check valves are specifically designed for OEM use. These valves offer outstanding performance at a great price! Valve bodies are all brass with stainless steel springs and glass-filled fluoropolymer poppet. High flows are insured with oversize discharge holes. Final assembly is a swaging operation, which insures long life, but does not allow disassembly. 450 PSI max pressure, 400°F max. temperature.

B2 Diagram

Please note that the "barrel" length of the "B2" valve is shorter than our Super-Chek® line, so the OEM must insure that any "skirt" on the tank fitting is clear of the valve discharge holes (see diagram at left). Otherwise, potentially damaging backpressure may build up in the compressor discharge line and compressor head.
