Control Valve Video

The DATIAN Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.

ZHD Multi Stage Cage Sleeve Control Valve

ZHD Multi stage Cage Sleeve Control Valve, applied with multi-cage sleeve type spool or axial labyrinth spool, multi-layer pressure reducing. It controls the medium flowrate, reduces noisy caused by high pressure air or steam, qualified in high pressure medium occasion. It can be applied with multi-spring pneumatic diaphragm actuator or electric actuator.

ZHT Double Stage Cage Control Valve

ZHT Double stage Cage Control Valve, are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.

ZHM Single-stage Sleeve Control Valve

ZHM Single-stage Sleeve Control Valve, with high stability, easy maintenance and wide application. It can be designed as balance type for eliminate static unbalance, with damping effect, reduce valve vibration, can be applied in occasion with large pressure difference, can apply with multi-spring pneumatic diaphragm actuator or electric actuator, etc.

water power control valve

Water power control valve is a general term, a type of automatic control valve which is composed of a main valve and its external needle valve and guide valve. The working state of the hydraulic control valve is generally in the normal state, the normally open state, and the floating state, and mainly relies on the adjustment between the main valve and the needle valve or the pilot valve to control the water flow state.

multi-purpose water pump control valve

Multi-purpose water pump control valve is an intelligent valve installed in the water supply outlet of the high-rise building water supply system and other water-repellent systems to prevent backflow, water hammer and water hammer.

JD745X diaphragm type multi-function water pump control valve has three functions of electric valve, check valve and water hammer canceller, which can effectively improve the safety and reliability of the water supply system. The technical principle of slow opening, quick closing and slow closing to eliminate the water hammer is integrated to prevent the water hammer and the pump water hammer from being opened. Just operate the pump motor to turn on the button, the valve can automatically open and close according to the pump operating rules, the flow is large, the pressure loss is small. Diaphragm type is suitable for valves below T600 caliber.

APPLICATION RANGE

The multi-purpose water pump control valves are widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.

WY Series Temperature And Pressure Reducing Valve

WY Series Temperature and Pressure Reducing Valve is a new generation product developed by our company to absorb the advanced technology and structure of temperature reduction and decompression at home and abroad. It consists of four parts: a temperature reducing pressure reducing valve, a steam pipe, a desuperheating water pipe and a heat regulating device.

WY Series Temperature and Pressure Reducing Valve, is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allow high-pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various applications. Gas pressure regulators are used to regulate the gas pressure and are not appropriate for measuring flow rates. Flowmeters, Rotometers or Mass Flow Controllers should be used to accurately regulate gas flow rates.
