25h37nzh (NO)/25h38nzh(NZ) Two-seat control valve. fl. with mem.isp.mech. PN16 Tmax=+300oC (w, g)

25h37nzh (25h38nzh) is a two-seat flanged control valve with a diaphragm actuator designed for use at central and individual heating points, ventilation systems of greenhouses and in other areas of the national economy for automatic regulation of technological processes.

The balance of the plunger in the presence of two seats ensures stable and reliable operation when regulating the flow of the medium.

• Nominal pressure: 1.6MPa.
• The working stroke of the plunger: DN-25 - 16mm, DN 40 and 50 - 25mm, DN 80 - 40mm.
• Working medium: water, air, steam, liquid and gaseous media.
• Type of diaphragm actuator(MIM): DU-25 - MIM 200, DU 40 and 50 - MIM 250, DU 80 - MIM 320.
• Working environment temperature: from -15 to +300 g
