Frequently Asked Questions
Q
What is a Socket End Resilient Seat Gate Valve and how does it work?
A Socket End Resilient Seat Gate Valve is a type of gate valve featuring a resilient (rubber-coated) wedge that provides a tight seal against the valve seat. It operates by raising or lowering the wedge via a stem, allowing or blocking fluid flow. The socket end connection allows for direct pipe insertion and secure joining, making installation straightforward and leak-resistant.
Q
What materials are used in the main components of this gate valve?
The valve body and bonnet are made from ductile iron for strength and durability. The wedge uses DI+EPDM for resilient sealing, the stem is made from 2Cr13 stainless steel for corrosion resistance, and the stem nut, locating ring, and nut are all brass. Sealing components including the gasket, O ring, anti-dust ring, seal ring, and rubber ring are all NBR (nitrile rubber) for excellent fluid compatibility.
Q
What standards does this valve comply with?
This valve complies with multiple international standards. Face-to-face dimensions conform to API609, BS5155, DIN3202, and ISO5752. Flange connections are available to DIN, BS, UNI, ISO, ANSI, AS, and JIS standards. The mounting flange meets ISO5211, ensuring compatibility with a wide range of actuators and operators worldwide.
Q
What industries and applications is this valve suitable for?
This valve is suitable for a broad range of industries and applications, including HVAC systems, water supply and sewage treatment, food and beverage processing, chemical and petrochemical processing, power generation and utilities, paper and pulp manufacturing, and shipbuilding. Its reliable sealing performance makes it especially valuable in applications where leak prevention is critical.
Q
What is the working pressure rating of this gate valve?
The Socket End Resilient Seat Gate Valve is rated at PN16, which is equivalent to 200 PSI (approximately 16 bar). This pressure rating makes it suitable for most standard industrial and municipal water distribution systems, as well as HVAC and general fluid control applications.
Q
What size range is available and how are dimensions specified?
The valve is available in nominal diameters (DN) ranging from DN40 to DN300, covering the most common pipeline sizes used in industrial and municipal applications. All dimensions are specified in millimeters (mm), with face-to-face lengths following F5 and SABS standards. Please refer to the dimensions table above for exact measurements for each size.
