WJ41H German standard bellows globe valves for nominal pressure PN1.6 ~ 16MPa, flammable operating temperature of -29 ~ 350 ℃, explosive, toxic, toxic fluid, heat conducting oil, ammonia and other media. WJ41H German standard bellows globe valves are widely used: petrochemical, textile, plastic and paper, power steel, rubber, printing and dyeing, natural gas and other gas systems, safe and reliable performance, widely used in ethylene glycol and other industrial fluids. Drive a manual gear transmission, electric, pneumatic. German standard bellows valve structure features 1, reasonable structure, reliable sealing, rugged double bellows seal design (bellows + filler), to ensure zero leakage of the valve stem. No fluid loss and improve plant safety equipment. And in accordance with international standards sealed. 2, the sealing surface Co based alloy, wear, corrosion, anti-friction performance, long service life 3, stem quenched and surface nitriding treatment, good corrosion and anti-friction properties; stem Lift position indicator, and more intuitive German standard bellows valve technical specifications manual electric drive mode design standards DIN3356 DIN3202 length of the structure connecting flange DIN2543-2545 test and inspection DIN3230 German standard bellows valve performance specifications Nominal pressure (MPa) Shell test Pressure (MPa) Sealing test pressure (MPa) Temperature (℃) 1.6 2.4 1.76 ≤350 ℃ 2.5 3.75 2.75 4.0 6.0 4.4 6.4 9.6 7.04 Note: Series valve connecting flange can be designed and manufactured according to user requirements.
