Three-forging ball valve

Product Description

Design Features: 1.Stopper on handle plus locking device for anti-misoperation and better security. 2. Blow out proof stem 3.Reliable and convenient operation 4. Entire API**7 fire safe design 5.Anti-static device between stem and ball 6.End connection:Thread,SW,BW( extended stem) Valve Performance： 1. HVOF(High Velocity Oxygen Fuel Thermal Spray)technology is used to coat both ball and seat with superhard chrome carbide or tungstencarbide, enable both surfaces to reach an maximal hardness of HRC*5. Coating, with same thermalexpansion ratio of ball,will not drop off even big temperature change occur within medium. Painting can be CR alloy,Ni alloy,Babbittmetal,Ceramics etc. according to requirements of customers. 2. An advanced grinder with emery powder as grinding agent is appiled to polish the ball and seat one for one, ensure both surfaces fit well and sealed perfectly. 3. Suitable for high temperature,high pressure,antiseptic,particles and fiber medium also dusty and high viscosity medium.Possess an effective capability to shear and remove any particles and material on ball surface, guarantee a quick cut off and control of the medium. 4. Super-wearproof and washing proof, produced with excellent performance of high temperature resistant(*0℃***0℃),corrosion resisting(salt corrosion,acid corrosion,caustic corrosion etc.),highpressureresistant(6.4Mpa**2.0Mpa)， 5.Suitable for oil,chemical,petrochemical,metallurgy,light industry,oil refining,power plant,food,pharmacy,papermaking,minerals filed etc. 6. Suitable for freshwater,sewage,seawater,air,steam,food,pharmacy,chemical and various oil,Acid-Bases and salt medium etc.
