Lockup device, manual operation, in order to prevent misoperation, valve can be equipped with padlock device.
Anti-static structure, when a fire break out, the metal seal forms to prevent large leakage of media.
Valve body and stem can finish emergency injection seal, through the grease injection valve, the stop-leak compound can achieve a short-time
seal, therefore buying time handling the scene.

RAYS Through Conduit (T.C.) Slab Gate Valves are manufactured with a full bore port, rising stem OS&Y and with floating seats and gate, pressure energized, for a bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.
This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
The resilient seat butterfly valve, also known as a centerline butterfly valve, is a component used for controlling flow and isolating sections in piping systems. The structural feature of the centerline butterfly valve is that the stem axis, the center of the butterfly disc, and the center of the body are all aligned in the same position. This design is simple and easy to manufacture. A common example of this type is the rubber-lined butterfly valve.
