Frequently Asked Questions
What pipeline sizes are compatible with these valves?
These valves are available in a broad range of nominal sizes from DN50 to DN600, engineered to accommodate diverse pipeline system configurations.
What pressure ratings are supported?
The valves support ASME 150LB to 600LB and PN16 to PN63, allowing reliable deployment in both standard and high-pressure industrial environments.
Which manufacturing standards are followed for dimensions and connections?
Face-to-face dimensions strictly adhere to API 609 and ISO 5752. Flange connections follow ASME B16.5, and the top mounting flange complies with ISO 5211 for actuator mounting.
What body and disc material options are available?
Both body and disc components are available in Carbon Steel (WCB A216), Stainless Steel (SS304, SS316, SS304L, SS316L), and Duplex Stainless Steel (2507, 1.4529).
What actuator options are available for operation?
Due to the low torque operation design, these valves can be easily configured with manual Hand Levers, Gear Boxes, or automated Electric and Pneumatic Actuators.
How does the offset axis design enhance valve sealing?
The offset axis configuration reduces friction during cycling and provides a tight mechanical seal, effectively minimizing leakage under extreme temperature and pressure conditions.
