Product Description
Application:
The series of this valve are sanitary pneumatic or manual butterfly valves,which are widely used in stainless steel pipeline system to control and regulate medium flow.
Work principle:
This kind of valve can be handled by a pneumatic actuator. Pneumatic actuator is to covert the axial movement of piston to be 90 degree rotation of valve shaft, so that the valve can be open or close to achieve the requirment of control and open /close for the pipeline system. They have three type of actator: normally open (NO), normally closed (NC), air/air(A/A)
Stanard Design:
Various standards of valves can be provided to clients: DIN, 3A, SMS, ISO/IDF, BS/RJ, ASME/BPE etc.
The parts of vave usually include two pieces body of valve, disc, gasket of valve disc, two bush, and the entire valve is assemble together with bolts and nuts.
The series of NUOMENG butterfly valve: welded, clamp, male, weld/male, union/male, etc.
The series of actuator: 1. stainless steel pneumatic actuator specification: φ85, φ108 and φ133. 2. Aluminum pneumatic actuator, specification:ZT050D,ZT063D,ZT075D,ZT088D, ZT100D, ZT115D. 3.Electric actuator, specification:HL-05,HL-10, HL-20.
Actuator is fixed in the valve (by a bracket and bolts).
The specification of NUOMENG manual handle as follow:
1.Pulling handle,we can supply two kinds of specification(you can found the details on page 191)
2.Multi-position stainless steel handle can be used on the specification as follows:
DN10-DN100/3A 3/4"-4"/SMS19-102/DS1"-4"/ISO,IDF Φ19-Φ108
3.Multi-position plastic handle can be used on the specification are the same as the stainless steel multi-position handle.
The handle is fixed by a bolt.
