Product Description

BS5163, often referred to as ‘Specification for Resilient Seated Gate Valves for Water Supply and Gas’, is a comprehensive document published by the British Standards Institution (BSI). The operation of a BS5163 gate valve involves raising or lowering a gate or wedge inside the valve body to control the flow of water. When fully closed, the gate creates a tight seal against the resilient seat, preventing the passage of water. Opening the valve raises the gate, allowing water to flow through the pipeline.

Design and Construction Requirements

The standard specifies that resilient seated gate valves should be designed with a body made from ductile iron or steel, ensuring robustness and resistance to internal and external pressures. The valve’s seat is composed of a resilient material, typically an elastomer like EPDM, NBR, or others, which provides excellent sealing properties and durability even under fluctuating temperatures and pressures.

Features

1. Resilient Seating: BS5163-compliant gate valves feature resilient seats made of materials such as EPDM or NBR, which provide a reliable seal against leakage, even under varying pressures and temperatures.

2. Ductile Iron Construction: These valves are typically constructed from ductile iron, a material known for its strength, durability, and resistance to corrosion, making them suitable for demanding operating conditions.

3. Non-Rising Stem: China BS5163 gate valve often come with a non-rising stem design, where the stem does not move vertically during operation, allowing for compact installation in confined spaces.

4. Rising Spindle: Some versions of BS5163 gate valves may feature a rising spindle design, which provides visual indication of the valve position and facilitates manual operation when necessary.
