Fire protection gate valves
Select by stem design, supervisory function, connection and nominal pipe size. Every size is shown in both DN and inch notation for easier international sourcing.
International product families
Domestic codes remain visible only as factory references. Product names follow common international terminology so contractors and distributors can identify the required valve quickly.
Grooved-end gate valves with a supervisory switch for electrical open/closed position monitoring.
Flanged-end gate valves with a supervisory switch arrangement for position monitoring.
Non-rising stem gate valves for installations where a compact operating height is preferred. Grooved and flanged options are available.
Outside screw and yoke gate valves with an exposed rising stem that provides a clear visual indication of valve position.
Size & connection matrix
Factory model references are provided for quotation matching. Confirm pressure rating, groove profile, flange drilling, face-to-face dimensions, switch specification and approvals before ordering.
