Product Description
cast steel full weld Ball valve st37 for heating supply 1.Products showing THe weld Ball Valve has been widely is intalled on the pipelines od water supply,vapour,central heating ect (ISO 9001:2000 certifiction) 2.The data about our products Valve bady:ST37 Ball:SS304 Stem:SS301 Valve seat:PTFE+20%C “O"sealing ring: Viton 3.Features and Applications our welded ball Valves can satisfy the requirements of heating systems, e.g.: * Main pipelines of heating pipes * Cross channels of heating pipes * Heat exchanger station and any long distance operation station. For the transmission of hot water and two kinds of mixed media (water, air or nature gas),Limited to Max.4.0 MPa and 200°C. For the transmission of natural gas and one medium, from -30°C to 60°C,and even up to 150°C using specially designed ball valves. 4.Technical Introduction The ball valve is designed as fully welded structure, which can prevent the leakage of medium. * The valve seat is floating and spring-loaded. The seal is made of soft seal materials of PTFE+20%C and Viton B.The seat is tightly abutted against the ball surface by the Pressure of a spring, so that even if the media is in low pressure, a reliable sealing can be assured for the ball valve. Double piston effection and double seal (two-seal seat) are adopted in specially designed valve seat to realize double sealing, which makes the tightness of the ball valve more advantageous and the operation easier. * A floating ball is adopted for DN15~DN200,and a stem and trunnion ball is adopeted DN200 and above,which can ensure the accurate position fo different size ball.In other words,the sealing performance,low torque value and operability can be guaranteed. * The sealing of the stem is fulfilled by two replacealbe O-rings and packing consisiting of PTEE+20% C or flexible graphite,which can realize a multiple sealing to ensure the stem is tightly sealed without any leakage. Flexible graphite. as the packing seal material,is fire procf effect,and is specially suitable for fuel gas systems. * The mater als used for the valve body and pipelines are the same(carbon steel or SS steel),valve body and stem adopt SS steel and the packing adopts PTEE+20%C which is corrosion-resistance or flexible graphite. 5.Operation Modes Lever,Gear,Electrical actuator 6. ISO9001&14001approved 7.Packaging seaworthy plywood case fumigation-free wooden pallet woven bags We also can give you other packaging depend on your need. 8. Delivery timely 9.No extra cost Honesty is the principle of corporate survival We expect customers to establish long-term friendly and cooperative relations 10.Quolity is life 1. We are factory,the manufacturer of casting flanges and cast carbon steel gate valves. 2.We can complete the process from casting to machining independently.But other factories,for examples most of factories in wenzhou China ,the casting and machining were separated .So we can guarantee quality of the valves and delivery period. 3.We conducted prior to shipment of 98% sampling.Found problems,100% inspection.
