Analytical electric butterfly and characteristics of the pneumatic valve price adjustment

the characteristics of the electric pneumatic valve regulating butterfly:
light weight: made from ontology with senior nodular cast iron, weight than traditional control pneumatic valve weight about % ~ %, easy installation and maintenance.
flat type brake block: traditional butterfly pneumatic valve often wash the tube in the water after the external objects such as stone, wood, cement, iron filings, sundry sedimentation on the bottom of the pneumatic valve, such as the slots, easy to cause cannot close tightly and form slack phenomenon, adjusting electric butterfly at the bottom of the pneumatic valve adopt with water pipe flat design, not easy to cause debris deposition, make the flow unimpeded.
the whole plastic bags: the gate is made of high quality rubber, outsourcing, the whole Europe first-class rubber vulcanization technology make the gate to ensure accurate after vulcanization of geometry size, and rubber and ductile cast gate then, fall off not easily and elastic memory preferred.
the precision pneumatic valve, pneumatic valve adopts precision casting, precision pneumatic valve body geometry size of the internal guarantee without any finishing pneumatic valve's sealing.
electric adjustment butterfly
the advantages of a pneumatic valve, fluid resistance small, sealing surface of erosion and erosion by the medium.
2, open and close more effort. The flow direction of medium
3, not restricted, disturbed flow, reduce the pressure.
4, durable, simple to use.
5, the structure of the form is simple, short length, good manufacturing technology, wide application scope.
the disadvantage of electric pneumatic valve regulating butterfly
a, easy cause surface erosion and abrasion, maintenance is difficult.
2, appearance size is larger, open needs certain space, open and close time is long.
3, the structure is complex.
the reversing shunt with pneumatic valves according to the needs of the reversing shunt, the pneumatic valve can have three or more channels. Cock pneumatic valve and ball valve is suitable for this purpose, as a result, most of the pneumatic valves are used for reversing the shunt to choose one of this kind of pneumatic valve. But in some cases, other types of pneumatic valves, pneumatic valves as long as the two or more properly connected each other, also can use for reversing shunt.
butterfly type of pneumatic valve, press the sealing surface configuration can be divided into wedge gate type butterfly pneumatic butterfly valve and parallel disc type pneumatic valve. Wedge gate type butterfly pneumatic valve can be divided into: single gate type, double disc and flexible disc; Parallel slide type butterfly pneumatic valve can be divided into single ram and double ram. According to the threads of the pneumatic valve stem position, can be divided into pneumatic valve stem butterfly and non-rising stem butterfly pneumatic valve two kinds.
