What is Electric Resilient Seated Seal Gate Valve
An electrically operated resilient-seated gate valve is a flow-closing device used in fluid pipelines. Belonging to the wedge gate valve category, it is mainly used in industries such as water supply, metallurgy, petroleum, chemical, power, wastewater treatment, construction, and food processing.
Definition and Structure
An electrically operated resilient-seated gate valve is a fluid flow-closing device that uses a gate as the opening and closing element and achieves automated control through an electric actuator. Its core structure includes:
Valve body: Made of ductile iron, cast steel, or stainless steel, with an internal straight-through flow channel to reduce fluid resistance.
Gate: Covered with EPDM or NBR rubber, achieving sealing compensation through elastic deformation.
Steel: Made of stainless steel, equipped with three O-ring seals to reduce frictional resistance.
Electric actuator: Supports remote control and automated operation, sensitive and reliable.
Structural features:
Flat-bottomed seat: Prevents dirt accumulation and ensures unobstructed fluid flow.
Double-threaded stem design: Reduces operating torque and improves opening and closing efficiency.
Embedded copper nut: Enhances durability and prevents loosening.
Working Principle of Electric Resilient Seated Gate Valve
Open State: The gate disengages from the valve seat, and fluid flows through a straight-through channel with low resistance.
Closed State: The electric actuator drives the valve stem to rotate, causing the gate to move down to the valve seat. The elastic rubber layer deforms under pressure, filling machining deviations and achieving self-sealing.
Sealing Mechanism: Relies on the dual action of medium pressure and rubber elasticity to ensure zero leakage.
Core Advantages of Electric Resilient Seated Gate Valve
Reliable Sealing:
The elastic rubber layer compensates for machining deviations and adapts to changes in medium pressure.
Three O-rings seal the valve stem, reducing the risk of leakage.
Easy Operation:
The double-toothed valve stem and spiral bevel gear reduce opening and closing torque.
The electric actuator supports remote control, eliminating the need for frequent manual operation.
High Corrosion Resistance:
The valve body is coated with non-toxic epoxy resin, meeting drinking water hygiene standards.
The stainless steel valve stem and copper alloy internal parts offer excellent corrosion resistance.
Easy Maintenance:
Sealing rings can be replaced online when fully open, without interrupting water supply for construction.
Simple structure, highly interchangeable parts, reducing maintenance costs.
Applications
Municipal Engineering: Interception and regulation of tap water and sewage pipe networks.
Industrial Sector: Fluid control in petroleum, chemical, power, and metallurgical industries.
Building Systems: Automated management of building water supply, drainage, and fire protection pipe networks.
Special Environments: Food and pharmaceutical industries (compliant with DVGW standards), light textile industries.
