Series 30
Slide Gate (O-Port)
The Grey49 Series 30 is a UNI-DIRECTIONAL or BI-DIRECTIONAL Slide Gate valve. It's slide-through (‘o-port’) gate design provides consistent operation for your most difficult applications.
A seat ring guides the ‘o-port’ gate to isolate dense media. Our optional Bi-Directional design adds a second seat upstream of the gate.
Soft seats (Teflon, etc) can be specified to enhance shut-off capability.
Grey49 gates are engineered to withstand process conditions and line pressures with several material options and hardness ratings. Machined surfaces also ensure proper fitment and closure.
The custom-fabricated valve body is precision welded to form a robust ‘one-piece’ component. This unibody design eliminates potential leak paths, body splitting, and assembly misalignment.
Braided square packing materials are application-specific and stacked within a machined packing gland, providing exceptional sealing. Our engineers may specify optional scrapers when appropriate.
The valve bore is engineered to match the pipe I.D., whether it is Schedule 40 or heavy-duty rubber lined. There are no gate pockets, and flow passes through with minimal turbulence.
Grey49 bodies are custom fabricated with robust flanges and drilled/tapped flange holes. This allows for several installation orientations, including ‘dead-end’ service (no downstream piping needed).
Our valves are manufactured in-house, with mounting plates designed to accommodate any actuator type, brand and model. We also work with clients to provide 'bare stem' valves.
