Stainless steel threaded method orchid butterfly valve
Square Flange butterfly valves are widely used in wine production process, also used in: dairy products, beer, food, beverage, pharmaceutical and so on.
Butterfly valve works: the circular disc for opening and closing and with the turning of the stem to open, close and adjust a valve of the fluid channel. The butterfly valve butterfly plate installed in the diameter direction of the pipeline. In the cylindrical channel of the valve body, disc-shaped disc around the axis of rotation, the rotation angle between 0 ° ~ 90 ° rotation to 90 ° when the valve is open all license conditions.
Threaded flange butterfly valve design and parameters

Product selection points
, Butterfly valves, the main control parameters for the specification size.
2, butterfly valves, single plate damper, its simple structure, easy processing, low cost, easy to operate, but the regulation accuracy applies only to the ventilation and air conditioning system for the switch or the coarse adjustment of the occasion.
3, can be manual, electric or zipper operation, fixed at any angle of 90 ° range.
4, due to the uniaxial single valve plate, the endurance is limited, under big pressure, flow rate conditions, short valve life. The valve is closed ordinary points, insulation and thermal insulation.

Stainless steel spiral welded butterfly valve
Features and uses:
Spiral welded butterfly valve operating temperature 80 ° C water, the pipeline of drugs food and beverage and general corrosive media, and other media, the role of media used to truncate and connected piping. The butterfly valve can be divided into: sealing butterfly valves and non-sealing butterfly valve. The butterfly valve sealing Vice usually rubber, plastic and other flexible sealing material, and vice in the form of metal to metal seal. How it works: can drive remote control or by the handle for manual operation. Drive, there are three standards: NC-shaped, normally open and gas-gas type.
The main features are as follows:
1, the small size and light weight.
2, the structure is simple, open and close quickly.
3, regulating and sealing performance can achieve hierarchical control flow, adjust the performance.
4, fluid resistance and less operating torque.
5, open and close a number of tests up to tens of thousands of times, long life.
6, the seal can be replaced, reliable sealing the two-way sealed gas test leakage is zero.
7, sealing materials resistant to aging, corrosion resistance, applicable to a variety of media.
