The pressure is lessen than atmospheric pressure, and the tension drop on the disc must not exceed one kgf / cm2. The operating temperature of the medium depends on the procedure in which the system is utilized. The temperature generally does not exceed the selection of -70 ~ + one hundred fifty ° C. The simple specifications for this style of valve are to make sure a substantial degree of tightness in the relationship and the tightness of the framework and gasket materials. Vacuum valves can be divided into four groups in accordance to media stress:

one) Low vacuum valve: medium pressure p = 760 ~ 1mmHg

2) Medium vacuum valve: p = 1 × 10-3 mm Hg.

3) Substantial vacuum valve: p = one × 10-4 ~ 1 × 10-seven mm Hg

four) Ultra-significant vacuum valve: p≤1 × 10-8 mm H


>Vacuum valve commonly made use of in the valve stem for linear movement of vacuum bellows world valve. Gate valves are far more minimal, but for larger diameters, ball valves, plunger valves and butterfly valves are also readily available. Plug valves for vacuum valves have not been promoted, for the reason that the plug valves want to be lubricated with oil, so that oil vapor may well enter the vacuum process, Standard Glove box which is not permitted. Vacuum valve closures are sealed with rubber or metallic seals. The bellows of the bellows globe valve are designed of stainless metal, superior zinc brass JI80, plastic and other resources. Compact-diameter (diameter below ten mm) globe valve closures can be sealed with a diaphragm. Reduced and medium vacuum can use spherical plug valve


>The vacuum valve has the subsequent feature


>The pressure is reduce than atmospheric force, and the force fall on the disc need to not exceed one kgf / cm2. The working temperature of the medium relies upon on the procedure in which the device is made use of. The temperature generally does not exceed the selection of -70 ~ + one hundred fifty ° C. The main valves of Shanghai Shenhong Valve Co., Ltd. are: strain reducing valve (gasoline strain cutting down valve, adjustable stress reducing valve, bellows reducing valve, piston decreasing valve, steam minimizing valve, pilot lessening valve, air Strain lowering valve, nitrogen tension reducing valve, water strain lowering valve, self-operated pressure lowering valve, proportional strain reducing valve), protection valve, thermal insulation valve, cryogenic valve, ball valve, globe valve, gate valve, verify valve, butterfly valve, filter Unit, discharge valve, diaphragm valve, plug valve, plunger valve, balance valve, regulating valve, lure valve, pipe clamp valve, blow down valve, exhaust valve, mud discharge valve, pneumatic valve, electrical valve, significant strain valve, medium Force valve, reduced pressure valve, hydraulic regulate valve, vacuum valve, rubber lined valve, fluorine lined valve. The primary specifications for this type of valve are to guarantee a high degree of tightness in the link and the tightness of the framework and gasket conten


>Vacuum valve extensively used in the valve stem for linear movement of vacuum bellows globe valve. Gate valves are much more constrained, but for larger diameters, ball valves, plunger valves and butterfly valves are also readily available. Plug valves for vacuum valves have not been promoted, mainly because the plug valves will need to be lubricated with oil, so that oil vapor might enter the vacuum process, which is not authorize


>Vacuum valve closures are sealed with rubber or metal seals. The bellows of the bellows globe valve are built of stainless metal, substantial zinc brass JI80, plastic and other products. Tiny-diameter (diameter underneath 10 mm) globe valve closures can be sealed with a diaphragm. Lower and medium vacuum can use spherical plug valve


>The vacuum valve has the next qualities: The tension is reduce than atmospheric force, and the tension drop on the disc must not exceed 1 kgf / cm2. The working temperature of the medium depends on the system in which the device is employed. The temperature usually does not exceed the selection of -70 ~ + one hundred fifty ° C. The simple requirements for this form of valve are to make sure a high diploma of tightness in the connection and the tightness of the structure and gasket substance.
