Stationary _ hard seal pneumatic valve pneumatic components factory valve industry

Pneumatic pneumatic valve fixed hard seal pneumatic valve overview: fixed hard seal pneumatic valve is valve industry combined with pneumatic components factory product structure characteristics and function requirements, both at home and abroad on the basis of the secondary development in pneumatic valve free maintenance, security and so on has got great improvement. Fixed hard seal pneumatic valve executive standard: design and manufacturing standards: GB12237, API 6 d, DIN, JIS standards, etc. Structure length standard: GB12221, ASME B16. 10 and so on. The flange standard: GB9113, HG20592, HG20615, JB79 and ASME B16. 5, etc. Butt welding standard: GB12224 and ASME B16. 25 and so on. Product size: (~ 48 '), NPS2 ~ NPS48 inches) 。 Product pressure: PN1. 6 ~ PN42。 0MPa（ Class150Lb ~ Class2500Lb) 。 Products applicable temperature: - 29 ℃ ~ 600 ℃ stationary hard seal pneumatic valve body material: cast steel, WCB, LCB, CF8, CF8M forged steel: A105, LF2, 304, 316 duplex stainless steel, such as special material etc, can also according to customer requirements material production and manufacturing. Fixed hard seal pneumatic valve internal parts of the material: carbon steel ENP plating, Cr13 stainless steel, 304/316 stainless steel, dual phase steel and other materials, can also according to customer need to customize special material. Fixed hard seal pneumatic valve features: (1) valve body, valve cover, stem, seat position such as adopt double seal, safe and reliable. (2) the valve stem and the aerodynamic body connected by pin shaft torque, reliable transmission. (3) stem fly out proof design. (4) stop pin structure is used in connecting plate under the action of the valve driving force in the resellers, completely offset, drive to use more stable. (5) fire prevention structure. 6. Automatic pressure relief function. All landowners self-lubricating bearing structure, can effectively reduce the valve operating torque. Today under the one-piece stem, aerodynamic body is more stable, use more reliable. Pet-name ruby anti-static structure. Attending function DBB. ⑪ stem free maintenance, stem seal structure of seal ring insulation, external set on the valve stem, increase the stem seal effect. ⑫ seat on the structure between the seat and the aerodynamic body due to wear and tear, such as medium scour on the outside of the seat in the form of fat injection, strengthen the seat sealing performance. Fixed hard seal pneumatic valve applicable medium: water, oil, natural gas, acid medium, high temperature medium, such as seawater environment. Fixed hard seal pneumatic valve applications: oil, food, medicine, petrochemical industry, natural gas, steel, electric power, metallurgy, environmental protection, urban construction, papermaking and other fields, stable performance, safe and reliable.
