First, detailed materials of the product [the pneumatic membrane regulates the angle valve ]:


Type of the products: ZJHJ

Name of product: The precise small-scale pneumatic membrane regulates the angle valve

Characteristic of the products: ZJHJ precise small-scale pneumatic membrane regulates the angle valve single seat valve and adopts the top to lead the structure, worthy of using the executive body of many springs. Have structure compactness , light , movement sensitivity , fluid passway streamlined to present S , pressure lose little , valve capacity heavy , flow characteristic accurate , disassembly and assembly advantage such as being convenient. Apply to the accurate craft parameter of controlling such medium as the gas , liquid ,etc. keeping in setting value such as the pressure , flow temperature , liquid location extensively. Especially suitable for allowing the letting out amount to be small , press the high viscidity not big of difference in front and at the back of the valve, the regulation with suspended substance and particle and form material and fluid, can avoid forming burnt , stop up , convenient self-purification and occasion washed .

Second, valve body:

Form : The angle shape single seat is cast the valve
Nominal and open directly: 20-300mm
Nominal pressure: PN1.6 4.0 6.4MPa
Connect the form : The flange presses JB78-59 JB 79-59
Material : HT200 ZG230- 450 ZG1Cr18Ni9Ti ZG0Cr18Ni12Mn2Ti


Third, have the valve to cover:

Normal atmospheric temperature type: -20 20 +200 degrees Centigrade
Heat dissipation type: -40 40 +450 degrees Centigrade
Press the form of overlaying: Compressing tightly type of the bolt
Packing : The polytetrafluoroethylene (PTFE) packing of Model V, soft graphite, stainless steel corrugated pipe.

Fourth, package in the valve:

Core pattern of the valve: Have and lead the post filling of the single seat in type valve core
Flow characteristic: Wait for the percentage characteristic , linear characteristic and make the characteristic quickly
Material : 1C18Ni9Ti 0Cr18Ni12Mo2Ti

Fifth, executive body:

Pattern: Many spring type membrane executive bodies
Diaphragm material : The man inserts fine rubber to strengthen the dacron to accumulate things
Spring range : 0.02.10 , 0.08.24MPa
Support atmospheric pressure strength : 0.14, 0.16, 0.28, 0.40MPa
The source of the gas is connected: Interior whorl M10 * 1
Environment temperature: -30 30 +70 degrees Centigrade
Function pattern of the valve : Angry - Opening type or angry - Closing type
Enclosure : Positioner, handwheel organization

Sixth , performance:

Letting out amount : The metal valve seat accords with standard ANSIB16.104IV grade
Smaller than 0.01% of specified Cv
Lack of: 3% (not take the positioner )
1% (take the positioner)
Linear: ± 5% (not take the positioner )
± 1% (take the positioner)
The remarks: Use the polytetrafluoroethylene (PTFE) packing of Model V
Adjustable range : 50:1
