Product Introduction: Flanged Check Valves
The J41H flanged stop valve is suitable for pipelines in the petrochemical, fertilizer, power, and various other industrial applications, which operate at nominal pressure of PN1.6～16.0Mpa and working temperatures of -29～550℃，for cutting off or connecting media. Suitable media include water, oil, steam, acidic media, etc. Operation methods available are manual, gear-driven, electric, and pneumatic.
Flanged Stop Valve, Features of J41H Flanged Stop Valve
1. Products comply with National Standard GB12235, featuring reasonable structure, reliable sealing, stable performance, and attractive appearance. 2. The sealing surfaces of the valve disc and seat are made of Stellite cobalt-based hard alloy surfacing, which is wear-resistant. 3. The valve stem is heat-treated and surface-nitrided, offering excellent corrosion resistance and anti-abrasion properties. 4. Various pipe flange standards and sealing surface types are available to meet different engineering requirements and customer needs. 5. The valve body material range is comprehensive, with fillers and gaskets selected rationally based on actual operating conditions or customer requirements, suitable for various pressure, temperature, and medium conditions. 6. The reverse sealing is achieved through threaded connections of the sealing seat or surfacing of the body with austenitic stainless steel, ensuring reliable reverse sealing. Filler replacement and maintenance can be performed without shutting down the system, offering convenience and efficiency without affecting operation.
