Frequently Asked Questions (FAQ)
Q1
What is the advantage of the offset axis design in this valve?
The offset axis design eliminates continuous contact between the disc and the seat during operation. This significantly minimizes friction, delivers tight bi-directional sealing to reduce leakage, lowers operating torque, and extends overall service life.
Q2
What sizes and pressure ratings are available?
The valve series is available in nominal diameters ranging from DN50 to DN600. It supports pressure classes from ASME 150LB to 600LB, and European standard ratings from PN16 up to PN63.
Q3
What international standards do these valves conform to?
These valves comply with API 609 and ISO 5752 for face-to-face dimensions, ASME B16.5 for flange connection standards, and ISO 5211 for top flange actuator mounting.
Q4
Can these valves be used in corrosive and high-temperature environments?
Yes. With body and disc materials available in Stainless Steel (SS304/SS316/SS316L) and Duplex Stainless Steel (2507/1.4529), combined with STL/2Cr13 metal seats and flexible graphite packing, they are purpose-built to resist corrosion and endure severe high-temperature and high-pressure duties.
Q5
Which actuation options can be configured with the valve?
The standard ISO 5211 mounting flange allows direct configuration with manual Hand Levers, Worm Gear Boxes, as well as automated Pneumatic and Electric Actuators to meet varying control requirements.
Q6
How does low torque operation benefit pipeline systems?
Low torque reduces the physical effort required for manual operation and allows smaller, more cost-effective pneumatic or electric actuators to be used, ultimately lowering system costs and energy consumption.
