Description


A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. Valves are the basic components in piping systems. Valve fittings, like pumps in technology, are often discussed as a separate category. The valve may be operated manually or with a hand wheel, handle or pedal, and may also be controlled to vary the pressure, temperature and flow rate of the fluid medium. The valve can perform continuous or repeated operations on these changes, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used as required by external inputs (I. e., to adjust the changing set point of the flow through the pipeline). The automatic control valve does not need to be manually operated according to its input and setting, so that the valve can accurately control the various requirements of the fluid medium. Valves can also be divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, dual phase steel valves, plastic valves, non-standard customized valve materials, etc.

◆ Product overview

J744X/J644X hydraulic, pneumatic angle type quick opening mud valve, is a kind of hydraulic source or pneumatic source for the actuator of the angle type cut-off valve. It is usually installed in rows on the outer wall of the bottom of the sedimentation tank to remove the sediment and dirt from the bottom of the tank. The piston of the valve hydraulic cylinder is L-shaped cup, with good sealing performance and durability. The valve sealing pair is also rubber sealing, without leakage. Remote control can also be achieved through the electric two-position four-way reversing solenoid valve. Easy to operate, safe and reliable.
