Ductile Iron Lift Check Valve Flanged End Ductile Iron Lift Check Valve 1. PRODUCT PROFILE The lift check valve is a valve which prevents the suction line from running empty, e. g. after the pump has been stopped. Priming the pump prior to a re-start is therefore no longer necessary. Spring-loaded lift check valves can be installed in the piping in almost any mounting position. Compared with swing check valves their head losses, are higher as the deflection of the flow is

Ductile Iron Lift Check Valve Flanged End Ductile Iron Lift Check Valve 1. PRODUCT PROFILE The lift check valve is particularly adapted for high-pressure service where velocity of flow is high. In this type of check valves, the piston disc is accurately guided by long contact and a close sliding fit with the perfectly centered dash pot. The walls of the piston and dash pot are of approximately equal thickness. Large steam jackets are located outside of the dash pot and inside

Wafer Type Dual Plate Check Valve 1. PRODUCT PROFILE The Dual Plate Check Valve is an all purpose non returnvalve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or life check valve. Wafer dual plate check valve can be mounted between the two pipes in both horizontal and vertical directions. The wafer type check valves are wafer-type valves with a short overall building length. Their excellent hydrodynamic properties

Wafer Type Check Valve 1. PRODUCT PROFILE Wafer type dual plate check valve is one type of non-return valve with two torsion springs added to each of pair valve plates, which close the plates quickly and automatically, preventing the mediums from flowing back. Wafer dual plate check valve can be mounted between the two pipes in both horizontal and vertical directions. The wafer type check valves are wafer-type valves with a short overall building length. Their excellent

DI Foot Check Valve 1. PRODUCT PROFILE Pump foot valve is also one type of check valve, which is vertically installed at the bottom of the pump pipe to prevent the water back flow and keep water level. Prosper Flow can design and manufacture the foot valve according to standard of BS5153 with sizes of 2”~12” (DN50~DN300mm). What is the function of a foot valve? A Well Piping Foot Valve is a one way or anti-siphon valve which is installed on the pick-up end of the water pipe

Small Size Threaded Ball Check Valve PN10/PN16 DN25-DN65 1. PRODUCT PROFILE The NBR rubber coating of the Stainless Steel ball allows for use with different viscosity and/or chemically aggressive liquids, with a temperature handling of up to 80℃. These valves are manufactured from Cast Iron with an epoxy coating, the ball is Stainless Steel with an NBR rubber coating. The connections on the ball check valve are threaded female BSP. Material Ductile iron/Cast iron Medium Water

Ball Check Valve 1. PRODUCT PROFILE A ball check valve functions by means of a ball that moves up and down inside the valve. The seat is machined to fit the ball, and the chamber is conically shaped to guide the ball into the seat to seal and stop a reverse flow. Ball check valves are often preferred for use in pumping stations that are rarely attended, since they demand only limited maintenance, typically if the ball makes noise caused by insufficient pump capacity or water

Wafer Typr Dual Disc Check Valve 1. PRODUCT PROFILE Wafer type dual plate check valve is one type of non-return valve with two torsion springs added to each of pair valve plates, which close the plates quickly and automatically, preventing the mediums from flowing back. Wafer dual plate check valve can be mounted between the two pipes in both horizontal and vertical directions. Wafer type dual plate check valve has features of compact structure, light weight and bidirectional

Ductile Iron Flanged End Ball Check Valve 1. PRODUCT PROFILE DI Ball check valve adopts Alu coated with rubber ball as its disc that rolls up and down in the valve port in the effect of fluids, achieving the valve open and close. Its sealing is very good, and even it is silent close without water hammer. Slide ball type check valve adopts full bore design, which makes it have big flow, small resistance, small head loss that is 50% smaller than that of swing type check valve.
