Fire Fighting System Use Ductile Iron Clamp Type Slide Ball Type Check Valve
Product introduction:
Fire fighting valve products are control accessories on industrial and building pipelines. Fire fighting valve is the most important controlled accessory on industrial and building pipelines, normally consisting of valve body, opening and closing mechanism, and valve cover. Simple structure and reliable sealing.
The HQ81X series slide ball type check valve adopts a rubber wrapped rolling ball as the valve. Under the action of the medium, it can roll up and down on the integral slide of the valve body, thereby opening or closing the valve. The sealing performance is good, and it closes when silencing without producing water hammer. The valve body adopts a full water flow channel, with high flow rate and low resistance. The loss of the faucet is 50% less than that of the rotary valve. It can be installed horizontally or vertically and can be used in cold water, hot water, industrial and domestic sewage pipelines. It is more suitable for submersible sewage pumps, with a medium temperature of 0-80 ℃. Can be installed at the water outlet to prevent backflow and water hammer damage to the pump.
