Design of Disc
Gate valves with NPS >2 are of flexible wedge gate; pav valve.pipe armaturen.
Gate valves with NPS <2 are of solid wedge gate.
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.
Gasket of Cover Flange
Carbon steel or stainless steel+ flexible graphite combined gasket is used for Class 150 gate valve；Stainless steel+ flexible graphite wounded gasket is used for Class 300 gate valve; Stainless steel+ flexible graphite wounded gasket is used for Class 600 gate valve, and ring joint gasket is also optional for Class 600 gate valve; Ring Joint gasket is used for Class 900 gate valve; Pressurized seal design is used for Class 1500~Class 2500 gate valve.
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.Belleville Spring Loaded Packing Impacting System
If being requested by the customer ,the Belleville spring loaded packing impacting system can be adopted for enhancing the durability and reliability of the packing seal.water seal gate valve.Spiral wound gaskets
Back Seating Design
PAV valve. 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<10 gate valves, and welded on seat can be also optional if being requested by the customer. Welded on seat is used for NPS<10 carbon steel gate valves .for Stainless steel gate valve, integral seat is usually adopted, or to weld hard alloy directly integrally. Threaded or welded on seat is also optional for stainless steel gate valve if being requested by the customer.
Stem Design
The stem is of integral forged design .The minimum diameter of the stem shall per the standard requirement .The connection of the stem and disc is T type .The strength of the connecting area is bigger than that of the T threaded part of the stem .
Stem Nut
Usually, the stem nut is made of ASTM A439 D2.It is also can be made of copper alloy if being requested by the customer .For large sized gate valves (NPS 10 for Class 150, NPS 8 for Class 300, NPS 6 for Class 600,NPS 5 for Class 900),rolling bearing is fitted at the two sides of the stem nut in order to minimize the open and close torque of the gate valve.
Special Gate Valve
Besides the common gate valves ,We can also makes cryogenic gate valve, Jacketed Gate Valve, Bellow Sealed Gate Valve, Extension Stem Gate Valve for underground application, Flat Gate Valve, etc.Water seal gate valve.By-Pass and Drain Connections,Indicator and Locking Devices.
