Products Details

1.Product overview:

708ME-ZAZPE Small flow control valve is a special control valve for the control of small flow, can control the flow of all kinds of gas, liquid, steam, KV value up to 0.005.Therefore, it can be used in many occasions where accurate control of small flow rate is needed, such as laboratory test equipment, or industrial equipment in mass production, to control the small flow rate of chemicals, dyes, flavors and other additives.

708ME-ZAZPE electric small flow control valve can also be specially used for SCR/SNCR flue gas denitration system, the use of the medium is generally 20% concentration of ammonia or urea, through the control of the upper computer, the electronic electric actuator output DC4-20mA control signal to accurately control the valve opening,Thus accurately adjust the amount of ammonia or urea injection, in order to achieve a higher standard of flue gas denitration efficiency, in line with the requirements of environmental protection of flue gas.

2.Structure and Principle:

This product is composed of two parts: multi spring pneumatic film actuator or electronic electric actuator and needle type single seat regulating valve.The actuator receives the external control signal,Push rod displacement, drive the valve stem, the valve core relative to the valve seat displacement,The flow rate into the valve body is changed to ensure that the production process is carried out according to certain procedures or requirements.

4.Product features:

1.The flow path of the valve body is strictly designed according to constant cross section and low flow resistance, so the pressure drop loss is small.

2.The spool adopts the enhanced stem oriented structure, so the work stability is good, especially can withstand the impact of high-speed fluid on the spool.

3.Actuators are evenly arranged around multiple springs and use high-strength rubber film actuators, which can accept 20-100kPa (3-15psi) standard pressure control signals.
