First , product [ZJHF three-way pneumatic valve, control valve
( Whether detailed materials on shut ) , shed the membrane regulating valve ].

Type of the products: ZJHF (H ) type

Name of product: The pneumatic three direct links dividing ( Shut), shed the membrane regulating valve

Characteristic of the products: ZJHF (H ) regulating valve of pneumatic three direct links meets and shunts two kinds of structure forms . The core structure of the valve adopts the window of thin wall of drum, adopt the direction to the side of the core of the valve, the three direct links valve can substitute two valves two times and a piece of three direct links to take over but wait until extensive application in some occasions, the daily two phase to the heat exchanger is regulated, can be used in simple matching to regulate . When the nominal put through foot-path and difference of pressing are smaller, meet the valve can be used for shunting the occasion, use interchangeably , but greater than 80mm and press to have the bigger distributary occasion left nominally and openly directly , can't exchange and use .

Second, valve body :

Body form of the valve: Cast the ball type valve in three direct links
Nominal and open directly: 25- 300mm
Nominal pressure: PN1.6 4.0 6.4MPa
Connect the form : The flange type presses JB78-59 JB 79-59
Material : HT200 ZG230- 450 ZG1Cr18Ni9Ti
ZG0Cr18Ni12Mo2Ti


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.

Fourth, package in the valve :

Core pattern of the valve: Gap core of Model V
Flow characteristic: Linear or when percentage
Material : 1Cr18Ni9Ti 0Cr18Ni12Mo2Ti

Five, Executive body :

Pattern: Many spring type membrane executive bodies
Diaphragm material : The man inserts fine rubber to strengthen the dacron fabric
Spring range: 0.02~0. 1, 0.04~0.20MPa
Support atmospheric pressure strength : 0.14 0.16 0.28MPa
The source of the gas is connected: M10* 1
Environment temperature: -30 30 +70 degrees Centigrade

Sixth , performance :

Letting out amount: Accord with standard ANSIB 16.104IV grade , is smaller than 0.01% of specified Kv value
Basic error: ± 1%
Lack of: 1% (take the positioner) 3% (not take the positioner )
Linear: Remarks of ± 5% (not take the positioner ) of ± 1% (take the positioner ): Use the polytetrafluoroethylene (PTFE) packing of Model V
Adjustable range: 30:1
