1、 Introduction of imported electric high performance butterfly valve

German "Locke" - imported electric high-performance butterfly valve product structure floating seat design, according to the direction of the pressure source, automatically adjust the seat position, to achieve the effect of double-sided pressure butterfly valve, and increase the service life of the seat, long service life. The valve shaft of butterfly valve is designed to prevent the fluid from entering the valve shaft and causing the valve shaft to jam. According to different working conditions, the high-performance butterfly valve can be made of different materials and properties. The valve seat is made of PTFE, rtfe, peek, metal and other materials, which is suitable for petrochemical, oil refining, air separation, CDA and other working conditions.

2、 Technical parameters of imported electric high performance butterfly valve:

Applicable temperature: - 50 ℃ ~ 450 ℃. Applicable medium: water, steam, oil, corrosive medium

Connection method: clamp / flange / lug

Leakage level: no bubble seal, zero leakage

Valve body material: carbon steel, cast steel, stainless steel CF8 / CF8M

Valve seat material: PTFE / rptfe / PPL / stainless steel / nickel base alloy

Butterfly plate material: stainless steel CF8 / CF8M

Stem material: stainless steel 17-4PH

Packing material: PTFE / flexible graphite

Material of shaft sleeve: stainless steel / PTFE

3、 Working principle of imported electric high performance butterfly valve:

The imported electric high-performance butterfly valve has a fire-proof structure, and can be connected by a pair of clip type or lug type single flange used for large pipe diameter and pipeline through the terminal. The valve seat is designed with movable inserts outside. The tighter the flange clamp is, the higher the pressure resistance is, and the better the sealing performance is. It is convenient and simple to replace the valve seat. The valve seat can be taken out just by removing the inserts. It is unnecessary to dismantle the valve plate and the valve shaft. The double eccentric butterfly plate with spherical sealing surface is adopted, and the single flexible lip type sealing seat is matched. It is suitable for the occasions requiring reliable sealing and good adjustment characteristics, Due to the design of double eccentric butterfly plate, the electric high-performance butterfly valve has tight sealing performance and long service life. It can be used to cut off or adjust the flow quickly.

4、 Advantages and characteristics of imported electric high performance butterfly valve:

[imported electric actuator]

① Powerful function: intelligent, adjustable, switch type;

② Small size: the volume is only about 35% of similar products;

③ Easy to use: single phase power supply, simple wiring; The original spherical protruding structure makes observation more convenient; Oil free, spot inspection free, waterproof and antirust, installation at any angle;

④ The protection device has double limit, overheat protection and overload protection. The total travel time is 15 seconds, 30 seconds, 45 seconds and 60 seconds. And with manual function;

⑤ Intelligent numerical control: the built-in module adopts advanced single chip computer and intelligent control software to directly receive the standard signal (4-20mA DC / 1-5vdc) from the computer or industrial instrument to realize the intelligent control and accurate positioning of valve opening.

[imported high performance butterfly valve]

① There is no need to add O-ring and metal parts to assist sealing;

② The lip seal structure can compensate the change of temperature and pressure on the valve;

③ There is almost no friction when sealing, so the torque is smaller and the sealing performance is better;

④ Single valve seat design, good elasticity, high reliability: lip seal structure can compensate for temperature and pressure changes, long service life, small maintenance, two-way bubble free seal;

⑤ Eccentric shaft and eccentric butterfly plate design: when the valve seat is opened or in the middle position, there is no contact between the valve seat and the butterfly plate, the upper and lower parts of the valve seat have no wear points, the torque is low, and the requirements for the operating mechanism are small;

⑥ Cut off and control both: with excellent control characteristics, flow characteristic curve proportional change, a wide range of adjustment, even for control can still be tightly sealed.
