Principle: 

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.

Features：

1. Seat is o-type ring and floating seat structure, make flat valve import and export seal; And the structure of the opening and closing moment for the common valve only 1/2, can achieve easily open and close the valve;

2. When full open, channel smooth to linear, flow resistance coefficient is tiny, the pressure loss, can connect cleaning line;

3. With the packing structure of sealing ability, without constant adjustment, features very light open and close and sealing is reliable, stuffing box place an assisting sealing grease injection structure, sealed performances absolutely reliable and get a true zero leakage;Solve the common valve packing place the most easily leak of evils;

4. Valve closed can automatically unloaded lumen high pressure, ensure safe operation;

5. Fully closed structure, protective performance is good, suitable for the requirements.
