Product Description
Silent check valves are fitted with a flow guide on the body.When the liquid enters from the inlet, push the disc to the outlet.When liquid stop into the export pipeline in the liquid flow rate will gradually slow down, due to the disc in the spring and disc right back in medium with quickly move to the left, before export medium flow rate to zero, to prevent the liquid flow back, so as to prevent water hammer occurs, achieve quiet closed effect, prolong the service life of the valve.
Features
01. the water flow channel inside the mute check valve body is straight and tends to streamline, which can improve the flow of the pipeline medium.
02. the disc opening and closing movement distance is short, can quickly open and close, the water hammer sound is small, the mute effect is excellent.
03. Ingenious design of valve body, reasonable structure, light weight, easy installation and good airtight performance.
Operating principle
When there is no medium flowing in the pipe, the disc of the silent check valve is closed by the action of a spring.
When the pipeline medium is flowing in the correct direction, the disc of the silent check valve is pushed by the fluid, and the disc is opened to allow the fluid to pass through.When the medium in the pipeline occurs counter-current, counter-current medium produces reverse thrust and the force of disc spring. Since the disc can only be opened in one direction, the two thrust forces will press the disc tightly on the sealing surface and prevent the media from flowing back.
SS314 Ductile Iron Nozzle Check Valve
Advanced dynamic design of single body with diffuser provides streamline flow and assures lower head loss.
Minimize the head loss to 0.016Bar upon 2M/ sec flow rate.
Brass or reinforced bearing reduce wearing problem during operation.
Hydrodynamic design ensures non slamming and water hammerless.
Stainless steel spring hidden in the diffuser under protection while valve in operation.
Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 Sec.
Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.
