Product Description

Valve Type:	Resilient seat gate valve	Structure:	Non-rising type
Standard:	AWWAC509	Workmanship:	Investment casting
Sealing direction:	Bidirectional	Sealing grade:	Zero leakage
Temperature:	-20°C < T < 120°C	Operation:	Handwheel

Characteristics

For resilient-seated gate valves, the gate plate generally features full encapsulation. Its rubber sealing surface uses elastic deformation to offset small sealing surface irregularities, ensuring a zero-leakage seal. Additionally, the valve stem is sealed with three layers of O-rings for reliable prevention of medium seepage.

Main Advantages

Flexible installation, adaptable to complex scenarios

Flange connection or welding connection can be used, and the installation method supports horizontal, vertical or buried installation. The overall structure is compact and lighter in weight compared to hard-sealed gate valves, reducing installation difficulty and costs.

Zero leakage seal for harsh conditions

The gate adopts an integral rubber coating process. The sealing surface compensates for processing errors and wear through elastic deformation, achieving a bi-directional zero leakage effect, especially suitable for municipal tap water and sewage systems.

Anti impurity accumulation, low maintenance

The flat-bottomed valve seat design is flush with the inner wall of the pipeline, preventing the accumulation of mud, stones, or fibers. This avoids opening/closing failures and reduces the frequency of cleaning and maintenance.

Packaging

We provide standard export wooden case packaging to ensure the safety of the valves during international transportation and long-term storage.

Application Scenarios

Widely used in the water treatment industry, including pure water preparation and sewage treatment plants. The epoxy resin coating prevents medium pollution, making it ideal for clean water, recycled water, and chemical dosing pipelines.

Frequently Asked Questions

What is the main benefit of a resilient seat gate valve?

The primary benefit is its zero-leakage sealing capability. The rubber-encapsulated gate deforms to fit the valve body perfectly, ensuring a tight seal even with minor irregularities or debris.

Why use a non-rising stem structure?

The non-rising stem design saves space as the stem does not move upwards when the valve is opened. This makes it ideal for underground installations or areas with limited vertical space.

Is the valve resistant to corrosion?

Yes, the valve body is typically sprayed with epoxy resin both inside and out, which provides excellent corrosion resistance and prevents contamination of the medium.

Can this valve handle sewage with solids?

Yes. The flat-bottomed seat design prevents the accumulation of impurities like stones or fibers, making it highly effective for sewage and rainwater systems.

What standards do these valves comply with?

Our resilient seat gate valves are designed to meet international standards such as AWWA C509, ensuring high quality and compatibility with global engineering requirements.

What are the available operation methods?

The standard operation is by a handwheel, but they can also be configured with gear operators or electric actuators depending on the application requirements.
