3.2The plug valve is driven by rotating the wrench plug rotating 90 DEG C to open or close.

3.3 The closed valve wrench clockwise rotation of 90 degrees.

3.4 The valve using the valve lining PTFE material, good sealing performance, the use of temperature ≤ 150 ℃.

3.5 The valve uses a wedge type plug, rotation torque is small, easy to seal, not easily stuck due to temperature change.

3.6 The adjusting shim structure, auxiliary valve cover pressing plugs to seal, and easy to repair.

3.7 The valve cover is provided with a V type of PTFE filler, lubricant oil installation fashion into a little, good sealing performance.

3.8 The quenching and tempering, chrome plating, enhance hardness, improve sealing performance and service life.
