A device with operating pressure from 0.25 psi to 200 psi which allows ow of liquid in only one direction preventing its ow in the opposite direction.more...
Spring check valve, This valves, when open, the annular area between the body & plunger available for flow, is equal to the nominal bore area. Therefore, unlike other spring loaded valves & conventional flapcheck valves, these valves offer lower head losses & maintains laminar flmore...
Ball check valves, As the pump starts, the ball moves out totally from the flow path when the pumping is on giving a full bore maximum flowdischarge with minimum head losses. (Fig. A). As the pump stops, the ball rolls back and seats perfectly on the rounded valves seat ensuring more...
There are many disk and seat designs available, in order to meet the requirements of different applications. The valve allows full, unobstructed flow and automatically closes as pressure decreases. These valves are fully closed when flow reaches zero, in order to prevent backflowmore...
Feature : Available in high temperature springs, heavy duty springs and spring-less configuration
Disc Check Valves from Forbes Marshall are spring loaded, non-return valves which allow flow only in one direction. When fitted at the outlet of traps discharging into closed systems, they prevent the back-flow of discharged condensate into the system.more...

EXPERT single plate, swing type Wafer Check Valves are used in pipelines to prevent backflow of the fluid. The valves are manufactured according to API 6D standard and tested in accordance with API 598. These valves are fast acting in closing, thereby maximizing protection to premore...
Check valves close the vacuum lines of uncovered suction cups. This maintains the system vacuum. Flow restrictors constrict the vacuum line. They are used predominantly in the handling of porous parts.more...
Non-return valve maintain the vacuum in the case of a power failure or a failure of the vacuum generator. Thye can also be used with energy-saving systems when handling non-porous materialsmore...
