Check Valves

Check Valves are suited for vacuum operations.

Vacuum check valves work with venturi vacuum pumps and switches to seal and maintain vacuum levels. With cracking pressure rated at less than 1 in. Hg., they allow air flow in one direction only. Valves can be manually operated or automatically controlled by vacuum switch. Able to be used in any orientation, valves come in 1/4 and 3/8 in. NPT sizes and are made of chrome plated brass with...

Foot Control Valve suits flows up to 80 gpm.

FC10-800 high-pressure water jet foot control valve is rated for pressures up to 10,000 psi. Pedal design includes latch to prevent accidental actuation, and allows operator to dump pressure almost instantly by rocking pedal forward. Dump ports on both sides help valve maintain stability when pressure is dumped. Disposable cartridge seal can be removed and replaced in less than 60 seconds.

Check Valve stops impure back flow.

Non-metallic, self-sealing Bio-Chek(TM) in-line check valve has inert flow path, making it suitable for stopping back flow in high purity, low pressure fluid transfer applications. Valve's smooth flow path minimizes shear and turbulence, and provides flow rate equivalent to 0.030 in. orifices. Cracking pressure is less than 3.5 psi. Valve checks against backflow pressures to 100 psi, and is...
