Q41N forged steel high-pressure valve,

Valve Manufacturing Co., Ltd. Shanghai crown ring forged steel high-pressure valve, Q41N forged steel high-pressure valve is mainly used for long-distance pipeline and city gas pipeline system transporting oil and natural gas. Because of the unique characteristics of long pipeline valves, thus fully taken into account in the design of its ability to withstand stress pipeline, as well as safety, weather resistance, long-term use of reliability; seal, structural design and another part of the business operation. Operation manual - worm drive, pneumatic, electric, gas \ liquid interaction, electro \ hydraulic linkage, and a variety of special forms of control. First, the high pressure valve product characteristics:? 1, All parts are forged. 2, download type stem, set back seal structure to ensure a reliable seal and prevent padding stem prolapse. 3, using mosaic seat. Seat behind the O-ring, make sure the media does not leak Second, high pressure valve product features: 1, double truncated and 2 emissions, safety decompression 3, a reliable seal 4, 5 fire protection design, cleaning pipes 6, an emergency seal 7, special valves 8, bonnet combined seal 9, sewage 10, take a long stem 11, 12 anti-static design, pipe stress safety to withstand three main parts material: Part name Material GB ASTM Body, bonnet WCB A216-WCB ring Nylon Nylon Sphere 1Cr18Ni9Ti SS 304 seat, stem 2Cr13 A246-416 O-ring rubber rubber studs 35CrMoA A193-B7 Fourth, the main performance specifications: Nominal pressure PN 16 32 MPa strength test pressure PT 24 48 MPa low pressure seal test force 0.6 MPa High pressure seal test force 17.6 35.2 MPa Suitable medium water, oil, steam Suitable temperature -40 ~ 80 ℃ high pressure forged steel ball valve http://www.ghval.com/product/qf/120.html Shanghai http: // www .ghval.com / productlist / qf-1.html
