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.
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, adapting to different engineering layouts. The overall structure is compact, and compared to hard sealed gate valves of the same diameter, it is lighter in weight, reducing the difficulty and cost of installation and hoisting. Corrosion resistant and wear-resistant, with a long service life.
Zero Leakage Seal — Suitable for Harsh Working Conditions
The gate adopts an integral rubber coating process, and the rubber sealing surface can compensate for processing errors, pipeline stress deformation, and wear caused by medium impurities through elastic deformation, achieving a bi-directional zero leakage sealing effect. Even under low pressure conditions, it can effectively block medium leakage, especially suitable for municipal pipelines such as tap water and sewage that require strict leak prevention.
Anti-Impurity Accumulation — Low Maintenance Cost
The bottom of the valve body adopts a flat bottomed valve seat design, which is flush with the inner wall of the pipeline, without grooves or dead corners, and is not easy to accumulate impurities such as mud, stones, fibers, etc. This avoids valve opening and closing failure caused by impurity blockage. For conveying systems containing impurities such as sewage and rainwater, it can significantly reduce the frequency of valve disassembly and cleaning, and reduce the workload of operation and maintenance.
Packing
Standard export wooden case packaging
Application Scenarios
Water treatment industry: in the process pipelines of pure water preparation and sewage treatment plants, it is used for the connection and disconnection of raw water, clean water, and chemical dosing pipelines. The valve body sprayed with epoxy resin can prevent medium pollution and is suitable for working conditions such as clean water and recycled water that require medium cleanliness.
Frequently Asked Questions
QWhat standard does this resilient seat gate valve comply with?
This valve is manufactured in compliance with AWWA C509, a widely recognized standard for resilient-seated gate valves used in water supply and distribution systems.
QWhat is the operating temperature range of this gate valve?
The valve is designed to operate within a temperature range of -20°C to 120°C, making it suitable for a wide range of industrial and municipal applications.
QHow does the resilient seat gate valve achieve zero leakage?
The gate is fully encapsulated with rubber using an integral coating process. The rubber sealing surface compensates for machining tolerances, pipeline deformation, and wear through elastic deformation, achieving bidirectional zero leakage even under low pressure conditions.
QWhat installation orientations are supported?
The valve supports horizontal, vertical, and buried installation. It can be connected via flange or welding, offering flexibility to adapt to various engineering layouts and site conditions.
QIs this valve suitable for sewage and rainwater pipelines?
Yes. The flat-bottom valve seat design eliminates grooves and dead corners, preventing accumulation of mud, stones, and fibers. This makes it especially suitable for sewage, rainwater, and other impurity-laden media, significantly reducing maintenance frequency.
QHow is the valve stem sealed to prevent leakage?
The valve stem is sealed with three layers of O-rings, providing a highly reliable barrier against medium seepage and ensuring long-term operational integrity even under demanding conditions.
