| Temperature: | -20°C < T < 120°C | Operation: | Handwheel |
The gate valve’s key operating component is the gate plate, which executes a linear reciprocating motion perpendicular to the direction of fluid flow. A defining operational characteristic of this valve type is that it is engineered exclusively for full-open and full-close functions, this design ensures unobstructed flow passage when fully open, and reliable shut-off performance when fully closed.
The valve achieves its exceptional sealing performance through an integral rubber-coated gate plate.
Standard export wooden case packaging is used to ensure the safety of the products during international transportation.
The resilient-seated gate valve is a widely utilized shut-off and isolation device across fluid handling pipelines in municipal, industrial, and building services sectors.
| Body | Plate | Stem | Stem nut | Seat | Temp (°C) |
|---|---|---|---|---|---|
| HT200/HT250 Cast iron | Ductile Iron | 20CR13 | Brass | EPDM Rubber | -20 ~ 120 |
| GGG40/GGG50 Ductile iron | Ductile Iron | SS304 | SS304 | NBR Rubber | -30 ~ 100 |
| WCB Carbon steel | WCB | SS304/SS316 | SS304/SS316 | FKM/VITON | -20 ~ 200 |
| CF8/SS304 Stainless Steel | CF8 | - | - | PTFE Rubber | -200 ~ 260 |
| CF8M Stainless Steel | CF8M | - | - | Brass | -30 ~ 350 |
The primary benefits include zero leakage sealing performance due to the rubber-coated gate, resistance to debris accumulation with its flat-bottom design, and a lightweight construction that simplifies installation and maintenance.
No, these gate valves are engineered exclusively for full-open and full-close functions. Using them for throttling can damage the resilient seat and lead to premature failure.
This valve features a non-rising stem design, meaning the stem rotates but does not move vertically during operation. This makes it ideal for installations with limited vertical space.
EPDM seats are excellent for water, steam, and dilute acids. For media containing oils or fuels, NBR or Viton seats are generally recommended.
The flat-bottom design mirrors the pipeline structure, which prevents the accumulation of silt, debris, or stones in the valve pocket, ensuring a consistent and clear flow path.
Yes, the resilient seat gate valve is designed for bidirectional sealing, providing reliable shut-off regardless of the fluid flow direction.
