What is API 602,BS 5352,ASME B16.34/B16.11/B1.20.1/B16.25 /B16.5 Forged Gate Valve
API 602,BS 5352,ASME B16.34/B16.11/B1.20.1/B16.25 /B16.5 forged steel gate valve is a valve whose closure member (gate) moves perpendicularly to the centerline of the flow passage. The gate's movement direction is perpendicular to the fluid flow, allowing the valve to be either fully open or fully closed but not suitable for flow regulation or throttling.
When closed, the gate forms a sealed space with the valve seat, blocking media flow; when open, the space between the gate and valve seat is fully opened, permitting free media passage.
The valve's opening and closing are achieved by rotating the stem, which raises or lowers the gate to control media flow.

Features & Performance
Advantages:
Low fluid resistance – When fully open, the sealing surfaces experience less erosion from working media compared to globe valves.
Lower external force required for operation – The medium can flow in either direction without restrictions.
Simple structure – The body design is straightforward, with good castability.
High-pressure resistance – Capable of withstanding high-pressure operating conditions, ensuring stable performance under high-temperature and high-pressure environments.
Corrosion resistance – Forged steel material offers excellent corrosion resistance, making it suitable for various media, including highly corrosive liquids and gases.
Disadvantages:
Large dimensions and opening height – Requires significant installation space due to its size.
Sealing surface wear – During operation, relative friction between sealing surfaces can cause scoring, leading to increased torque and potential leakage due to scratches on the gate and seat sealing surfaces.
Double sealing surfaces – The presence of two sealing surfaces increases machining, grinding, and maintenance complexity.
