Frequently Asked Questions
Q
What is a Rising Stem Resilient Seated Gate Valve and how does it work?
A Rising Stem Resilient Seated Gate Valve is a type of gate valve where the stem rises visibly when the valve is opened, providing a clear visual indicator of the valve position. The resilient seat (typically EPDM rubber) wraps around the gate disc to provide a tight, leak-free seal. When the handwheel is turned, the stem and disc move up or down to open or close the flow path.
Q
What is the maximum working pressure this gate valve can handle?
This Rising Stem Resilient Seated Gate Valve is rated for a working pressure of PN16, which is equivalent to 200 PSI. It is designed to meet this pressure rating reliably across its full range of operating conditions.
Q
What flange standards are compatible with this valve?
This valve is compatible with a wide range of international flange standards including DIN, BS, UNI, ISO, ANSI, AS, and JIS. The face-to-face dimensions comply with API609, BS5155, DIN3202, and ISO5752, making it suitable for global installations.
Q
What industries and applications is this gate valve suitable for?
This gate valve is designed for a broad range of industrial and commercial applications, including HVAC systems, water supply and sewage, food and beverage processing, chemical and petrochemical processing, power generation and utilities, paper and pulp manufacturing, and shipbuilding.
Q
What materials are used for the valve body and sealing components?
The valve body, disc, bonnet, yoke, and handwheel are all made from Ductile Iron for excellent strength and corrosion resistance. The seat, bonnet gasket, and sealing ring use EPDM rubber for reliable, leak-free sealing. The shaft is SS420 stainless steel, the wedge nut is brass, and packing is flexible graphite for high-performance sealing under varied conditions.
Q
What is the advantage of a resilient seated design compared to a metal-seated gate valve?
A resilient seated gate valve uses an EPDM rubber seat that fully encapsulates the disc, providing a bubble-tight shutoff even at low pressures. This design eliminates the need for precise metal-to-metal contact, reduces wear, requires less operating torque, and offers better resistance to minor debris in the flow media — resulting in longer service life and lower maintenance requirements compared to traditional metal-seated gate valves.
