	Standerds compliance
	Design and Manufacture: ANSI B16.34,API 6D Face to face: API 6D Flanged connection: 2~~24~to ANSI B16.5 22~,26~~36~to MSS-SP-44 to API 605 on request Test and inspection: API 6D Shell test 150Lb 450 PSI 300Lb 1125 PSI Seat test 150Lb 315 PSI 300Lb 815 PSI(Hydrostatic)80PSI(Air)

	Featutes
1.	Small in size,light in weight,compact in structure,easy in maintenance.
2	Two torsion springs are used excerting on each of the pair valves plates.Which close the plates quickly and automatically.
3	The quick-close action prevents the medium from flowing back and eliminates water-hammer effect.
4	This valves is short in length,so that it is rigid and easy to mount.
5	It is easy to install on pipeline which is laid horizontally or vertically.
6	This valves is tightly sealed without leakage under the pressure water test.
7	Safe and reliable in operation,high interference-resistance.
8	The connection dimensions of flanges accord with the standards of GB4216-84 GB4216.84
9	The face to face dimensions are in accordance with GB12221-89.ISO5752-82.The stem of the valves should be perpendicular to the horizontal level when the valves is mounted on horizontal pipeling.For vertical installation the direction of flow should be downward.
