All our gate valves have the back seating design. In most cases, the carbon steel gate valve is fitted with a renewable back seat. For stainless steel gate valve, the back seat is machined directly in the bonnet or is machined after welding. When the gate valve is at fully open position, the sealing of the back seat can be very reliable. However, as per the requirement of API 600, it is not advisable to add or change packing by the mean of back seating when the valve is pressure containing.


 

API Cast Steel Gate Valve product description

API Cast Steel Gate Valve (Generally flanged connection, but Butt-welding optional) are suitable for using on various kinds of pipeline from Class150 To Class2500, DN15 To DN1650 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/bevel gear/pneumatic or electric actuators could be chosen by needs. 
Just as the other Cast steel JIS gate valve, molded flexible graphite is used for packing. PTFE or combined packing material can be also used if being requested by the customer. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish (Ra 3.2μm). The stem surface, contacting with the packing, should be rolled and pressed after being precisely machined, so as to reach to the high finish and compactness (Ra 0.8μm) and ensure the reliable tightness of the stem area.

Wedge gate valve: Design complies with the requirements of API SPEC 6A and other relevant specification. End connection typeï¼Flange, inner-thread, collar and butt-weld both sealing faces of gate are wedge type structure , and hand wheel can be loaded to adjust the fastness of attachment of gate and valve seat. The sealing face of gate and seat is overlaying-welded with hard alloy with erosion and corrosion resistance. Main technology parameters Working pressure 2000~20000PSI Nominal bore 1 1/16³~7 1/16³ Suitable medium Petroleum mud natural gas etc
