Product details

The electric temperature and pressure reducing valve (WYS945H/Y) is mainly composed of valve body, valve seat, valve disc, valve cover and other parts, using double valve seat and conical plungerStructure, increased overcurrent area and adjustable ratio. There is a throttle hole cover inside the valve, which increases the pressure reduction range and avoids direct cooling of the cooling waterSpray onto the valve body to protect it.

Structural characteristics and applications

Electric temperature and pressure reducing valve（WYS945H/Y)Mainly composed of valve body, valve seat, valve disc, valve cover and other parts, using double valve seat and conical plunger

Structure, increased overcurrent area and adjustable ratio. There is a throttle hole cover inside the valve, which increases the pressure reduction range and avoids direct cooling of the cooling water

Spray onto the valve body to protect it.

Electric temperature and pressure reducing valves are mainly used in thermal power generation and are matched with third-generation temperature and pressure reducing devices. They are used to regulate pressure and temperature

When adjusting the temperature, it should be used in conjunction with the water supply regulating valve.
