WSVP two-way electric control valveDetailed product description：

WSVP high-temperature heat transfer oil, high-temperature steam two-way and three-way electric regulating valves are products specially developed for use in heat transfer oil steam temperature control systems in various industries such as printing and dyeing, chemical fiber, rubber and plastic, chemical industry, printing, etc. This product incorporates advanced technology from well-known foreign companies and adopts a dual sealing structure of stainless steel corrugated pipes and graphite packing. Therefore, it can effectively isolate the medium in the pipeline from the outside world, greatly improving the safety and reliability of product sealing. It is also suitable for regulating highly toxic, valuable, volatile, and permeable media in industries such as chemical, petroleum, and pharmaceutical.

The electric actuator receives 4-20mA control signals or switch control signals to change the opening of the valve, while feeding back the isolation signal of the valve opening to the control system for implementation.

Main features
Equipped with WL intelligent linear electric actuator, it has small size, full specifications, light weight, high thrust, easy operation, no adjustable potentiometer, high reliability, and low noise.  
The WL electric actuator adopts an integrated structural design with self diagnostic function, making it very convenient to use and calibrate.  
There is a digital display that shows the control signal value, feedback signal value, and electric manual operation value.  
WL intelligent electric actuator function: with fault diagnosis, alarm and protection functions for broken control signals. When the signal is interrupted, the actuator can be turned on or off; Or close; Or maintain; Or any predetermined position between 0 and 100%. Equipped with valve blockage fault diagnosis, pipe reporting, and protection functions.  
It has the characteristics of high adjustment accuracy and good adjustment performance, allowing a temperature difference of ≤ 150 ℃.  
In addition to the lining guide at the reading cover, the side of the valve core and the inner surface of the valve seat also have a guiding effect, with a large guiding area and reliable operation.  
The bellows sealing type forms a safe seal for the moving valve stem, blocking liquid leakage.
