Double-sealed hydraulic automatic control valves are in my digestion and micro-Slow Close Check Valve, Hydraulic Control Butterfly Valve, multi-function hydraulic control valves, valves and many other excellent performance, based on the latest products developed. It is a combination of electric valve, electric butterfly valve, as well as the non-return valve function, and through customs quickly closed gentle action to eliminate water hammer hazards, to protect the safety of the system pump is widely used in electric power, metallurgy, urban construction, water supply and drainage pumping stations and other automated systems.
Automatic double sealed sealed eccentric deputy for three structures, and tilted 75 degrees, reducing the trip valve clearance and shortened the distance between slip ring reduces the friction torque, and has anti-silt and automatic compensation for the effect of stress . Relief device and the valve closure gate interlock, automatic quick implementation of customs and buffer from the actual pump flow and head changes, without electrical components and external power. Devices less point of failure, operation and maintenance easy, simply open or turn off the host power supply pumps, valves or pumps in accordance with the rules automatically headstock. Selection of the key parts are stainless steel, copper alloys and other high-quality materials, and basic maintenance. Device can also be installed on valve position signal generator, sent 4 ~ 20mA analog valve position signal to the remote main control room, remote monitoring implementation.
