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.
Actuation
Hand wheel or gear box is usually used for gate valve actuation. Chain wheel and electric actuator can be also used for gate valve actuatuo if being requested by the customers.
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, intergral 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. The strength test if that area conforms to API 591.

Main Feature: 1) The seat ring uses the floating seat ring structure with O-seal ring sealed and pre-tightening force applied to have inlet and outlet dual-way sealed, and the open-close moment with this structure is 1/2 that of the common valves only, able to lightly open and close valve. 2) When fully opened, the valve's channel is smooth and linear,with an extremely small flow resisting coefficient and no pressure loss ,and the pipeline can be cleaned with hair-ball through it . 3) Automatic removal of the high pressure in the internal cavity when the valve is about to close so as to ensure safety. 4) Fully sealed structure leaves a good protective property, suitable for the requirement of 24-hour duty. Standard for gate valves: Design manufacture standard: API 6D Length of structure: API 6D Flange connecting end: ASME B16.5/ASME B16.47 Butt welding connecting end: ASME B16.25 Wall thickness: ASME B16.34 Inspection and test: API 6D Pressure and temperature rating: ASME B16.34 Product scope: NPS 2inch-NPS 48inch,CL150-CL2500 Main body material:WCB,LCB,WCC,WC6,WC9,CF8,CF8M,CF3,CF3M,A890 4A etc. Drive device: handle, bevel gear, electric, pneumatic, etc. Our Advantages: 1.We Are Factory: FYV has 3 production bases and 1 foundry which located in Wenzhou, Shanghai and Lishui city of China.
