The valve body adopts 304/316/316L stainless steel VF61 series

304/316L stainless steel series flange connection regulating valve: The single seat structure balanced valve produced by our company is equipped with a pressure balancing device inside, which can offset the thrust generated by the high pressure drop of the valve core, effectively solve the problem of high pressure on-site shut-off force, reduce the load on the actuator, extend the life of the actuator, and take heat transfer isolation measures according to the actual situation of domestic steam field, which is more suitable for domestic on-site use conditions. Suitable for chilled water, low-pressure hot water, domestic hot water, high-pressure hot water, seawater, hot oil, saturated steam, and superheated steam in open or closed circuits.
