Flanged connection solenoid valves, body made of cast iron and internal is stainless steel for water, steam and gases. Connections from DN40 to DN 150. Pressures from 0.3 bar to 8bar. Media temperatures from 0 to 75 ℃.
Cast iron fluid solenoid valves, are used in industrial applications that require high flow rates. Its damped hammer design and integrated pilot filter ensure reliable operation. Applicable to building control, HAVC, water factor, electricity factory, water conservancy project, environment protection water treatment, solar equipment, petrochemical industry etc.
Valve non-energised closed by spring power - NC. When energised , the pressure decomposes on the secondary side of the piston. Then the pressure differential (delta p) lifts the piston from the seat (orifice). These valves are used where a flow producing a minimum pressure drop is always present in a system or in systems where the valves full flow capacity is not required under low flow conditions.
