Sanitary Pneumatic/ Manual Butterfly Valve(YD)
Application
The type ofvalve series is a sanitarytype automatic or manual operation ofthe butterflyvalve series, widelyused in stainless steel pipe system to regulate the flow of a class ofvalves.
Working principle
This type of valve can be operated elther by an electric actuator or pneumatic actuator, or by a handle.
The electric actuator or pneumatic actuator converts the axlal movement of a plston to a 9O degree rotatlon of the valve shaft to reallze the control of the fluld of the plpe and the on / off task. The pneumatic actuator device has three standards: normally open (NO), normally closed (NC) gas/gas(AA).
A number of manual operating handle duckbil type through 15 degrees ofadjusting the position ofvalve mechanical lock in the open or closed 12 seats, to controlthe flow rate ofthe medium: Pull rod type manual operation with the handle through the 4 multi-function positioning, mechanical locking valve in its open or closed 4 seats, but also to achieve the purpose of controllingtheflowofmedia.
Design standard
There are a variety ofstandard valve series can be provided to the customer, that is, for the DIN standard series, 3A standard serles, ISO/iDF standard serles, BS/RJT standard series, ASME/BPE standard serles.
The valve components generally include: a two halves ofthe valve body, the valve chip, chip shaft shaft sleeve and shaft sealing ring, the entire valve ls assembled with bolts and nuts. Three plece valve also includes two fiange and two flange sealing ring.YlERKANG existing butterfly valves series are: Welded butterfly valve, butterly hoop type butterfly valve, outside the thread type butterfly valve, welding - the external thread type butterfly valve, by any- outside screw type butterflyvalve, butterflyvalve, such as three butterfly valves.The existing YEKactuator includes: 1 stainless steel pneumatic actuator, can provide aluminum with 19- 2732.pneumatic actuator, can provideZT050D,ZT063D,ZT075D,ZT088D,ZT100D,ZT115D six kinds of product specifications; 3 electric actuators can provide productspeclfications HL-05, HL- 10,HL-20.
The actuatoris fixed on the valve with a bracket and a screw.
YEKis currently used for manual operation of the handle specification type:
1 , pull rod handle, can provide two kinds ofdifferent product specifications;
2, anumberofstainless steelhandle aduckbill valvespecifications: DN10~DN100/3A3/4"~4"/SMS 19~102/DS1"~4"/S0.IDF 19-PhiPhi 108
3, a number of plastic handle of a duckbil valve specifications (with the same specifications: stainless steel duckbill type handle) handle ofmanual operation is cover/shaft system and a screw fixed on the valve with the valve.
