The products quote the standard:
" Y " type stop valve and non-return valve valve accord with ANSI B16.34. Inspection and testing according to API598, the mark presses MSS-SP-25. |
Product structure characteristic:
" Y " type has three kinds of valves to overlay the form of designing to forge the steel valve. The first kind is that bolt type valves are covered, the valve designed according to this kind of design form , its valve of body and valve are covered and joined with the bolt nut, the twining type spacer (316 inserts the soft graphite and makes ) is sealed. The customer can adopt the metal ring to join while having special demands . The second kind of design form is that welding type valves are covered, the valve designed according to this kind of form , its valve of body and valve are covered and joined with the whorl, weld and seal completely. The customer can be adopted and welded two connections completely while having special demands. The third since getting urgent valve cover for pressure, according to the valve that form designed, its valve of body and valve are covered and joined with the whorl , since the sealed ring is sealed to press inside.
Stop valves and non-return valves can be designed into " Y " type valve.
Adopt the following structure
The whole foot-path or contracting in the foot-path
Going up and down type and ball type non-return valve
It needs the built-in spring to press
Can dismantle the solid valve one
Feel relieved pressing plate pigeonhole suits of type by oneself
Have the sealed seat integrally
Support type of the bright pole ( OS Y)
Bolted joint , twine spacer person who seal valve cover , whorl join , weld person who seal valve cover and whorl press since getting urgent valve stamp in joining all
It accords with ASME to bear and insert the end B16.11
It accords with ANSI/ASME that the whorl joins the end (NPT ) B1.20.1
One changes variably for needle type , reducing expenditure type , ball type, stops the returning type in the valve
