They are used predominantly in the handling of porous parts. Gate valves are primarily designed for on-off services. The main restriction of a vacuum system is at the check valve. Check valves are also called non-return valves and one-way valves. Also known as vacuum breakers, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping. They can have a ‘stopping’ mechanism that can be shaped like a ball, disc, piston or poppet. 47149: Vacuum Check Valve - Universal. Type of valve employed depends on nature of fluid, flow control required, operating pressure and temperatures as well as surround atmosphere. Since most of the flow change occurs near the shutoff, the relatively high fluid velocity causes disk and seat wear and eventual leakage if the valve is used to regulate flow. This maintains the system vacuum. On the check valve that's at the end of the vacuum hose, which way does air flow? vacuum source to the plastic check-valve on the tank.
