Product Description

Product Specifications

Valve Type:	Resilient seat gate valve	Structure:	Non-rising type
Standard:	DIN F4	Workmanship:	Investment casting
Sealing direction:	Bidirectional	Sealing grade:	Zero leakage
Temperature:	-20°C < T < 120°C	Operation:	Handwheel

Characteristics

The core operating component of the gate valve is the gate plate, which performs linear reciprocating movements perpendicular to the fluid flow direction. This design ensures unimpeded fluid flow when fully open and dependable shut-off capability when fully closed.

Superior sealing performance is achieved via a fully rubber-encapsulated gate plate.

Key Advantages

✔

Exceptional Durability: Robust rubber-to-iron bonding structure exceeds national standards. Precision-cast from high-density ductile iron to withstand high pressure without cracking.

✔

Clog-Free Performance: Flat-bottomed valve seat design aligns with pipeline walls, eliminating debris collection spots and minimizing maintenance downtime.

✔

Lightweight Design: 20%–30% lighter than traditional models, simplifying installation and cutting labor costs.

Application Scenarios

This resilient-seated gate valve is widely deployed for shut-off and isolation in municipal infrastructure, industrial facilities, and building services systems.

Frequently Asked Questions

What makes the resilient seat gate valve "zero leakage"?

The valve uses a fully rubber-encapsulated gate plate that creates a tight seal against the valve body, ensuring zero leakage in both flow directions.

Can this valve be used for throttling or regulating flow?

No, this gate valve is engineered solely for full-open or full-close operations to ensure long-term sealing reliability and durability.

How does the flat-bottomed seat design benefit the system?

Unlike traditional valves with a groove, the flat-bottomed design prevents the accumulation of debris like stones or iron filings, ensuring a clog-free operation.

Is the valve suitable for high-temperature applications?

While standard EPDM seats handle up to 120°C, we offer VITON or PTFE materials that can withstand temperatures ranging from 200°C up to 350°C.

Why is ductile iron used for the valve body instead of standard cast iron?

Ductile iron offers superior strength and elasticity, making the valve 20-30% lighter and much more resistant to cracking under high pressure.
