High integrity compact.
Slab gate valve double block bleed.
By combining two valves into one body a twin valve design reduces weight and potential leaks paths while meeting the osha requirements for double block and bleed.
With the valve fully closed and pressure on both sides it is possible to bleed the pressure from the body cavity to check seat seal integrity and to achieve double isolation between the two sides and.
These bi directional double block and bleed slab gate valves are through conduit piggable and top entry.
Through conduit double block and bleed slab gate valves with fully protected seat faces for long lasting drop tight shutoff in liquid pipelines.
Valve associations usually choose to follow either api s or osha s definition but some have created their own handbook with their own definitions for industry terms.
The fabricated body allows for a wide selection of material choices.
Suitable for transportation pipelines for gas crude oil and oil products all valves are available in a variety of materials and configurations to meet your project requirements.
High integrity double block bleed plug valve.
The floating slab gate uses the natural force of line pressure to obtain a dynamically tight downstream seal in high pressure differential applications.
Product sheet how it works.
The m j valve model m 303 is an advanced fabricated body design slab gate valve manufactured and tested to api 6d.
Solid particles cannot penetrate into the body both when the valve is in the open or in the close position.
Through conduit double expanding gate valves are double block and bleed valves as they can grant zero leak towards the body cavity with pressure on the upstream and downstream side even when the valve is fully open.
