Design Feature:
Body and Bonnet Connection
The body and bonnet of Class 150~Class 900 gate valves are usually bolted bonnet design. And Class 1500~Class 2500 gate valves are usually of pressurized seal design.
Packing Seal
Molded flexible graphite is used for packing material. PTFE or combined packing material can be also used if being requested by the customers. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish(Ra 3.2um). 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 0.8um)and ensure the reliable tightness of the stem area.
Back Seating Design
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 API600, it is not advisable to add or change packing by the mean of back seating when the valve is pressure containing.
Seat
For carbon steel gate valve, the seat is usually forged steel. The sealing surface of the seat is spray welded with hard alloy specified by the customer. Welded seat is used for NPS Contact us if you need more details on Gate Valve.
