Product Description

Product Introduction

The opening and closing parts of the sanitary manual thread butterfly valve are rotated about 90° to open, close and adjust the fluid channel of a valve.
Sanitary manual screw butterfly valve is not only simple in structure, small in size, light in weight, material consumption, small in installation size, but also small in driving torque, easy to operate and fast, and can also have good flow regulation function and close sealing characteristics.
The sanitary manual screw butterfly valve has a small flow resistance when it is fully opened. When it is opened between about 15° and 70°, it can also carry out sensitive flow control. Therefore, the application of butterfly valves is very common in the field of large-caliber adjustment;
The movement of the valve plate of the sanitary manual thread butterfly valve has wipeability, so the welded butterfly valve can be used for media with suspended fixed particles, and can also be used for powder and granular media according to the strength of the seal.
Hygienic grade manual thread butterfly valve seal material with EPDM. EPDM (EPDM) has low density and high filling, aging resistance, corrosion resistance, water vapor resistance, water resistance to overheating, adhesion.
Sanitary manual thread butterfly valve is the middle line soft seal butterfly valve, the sealing principle is, the valve plate processing to ensure that the sealing surface has a suitable surface roughness value, synthetic rubber valve seat in the forming of the sealing surface suitable surface roughness value. When the valve is closed, through the rotation of the valve plate, the outer round sealing surface of the valve plate squeezes the synthetic rubber seat, so that the elastic deformation of the synthetic rubber seat is made as the sealing pressure to ensure the sealing of the valve.

The advantages of hygienic manual thread butterfly valve

1, the butterfly valve rubber seal ring and valve plate are imported parts, to ensure the performance and service life of the butterfly valve.
2, the use of high-precision CNC lathe body, to ensure the reliable interchangeability of the butterfly valve, avoid the trouble of replacing rubber and can not ensure its performance.
3, the valve stem is installed with nylon sleeve, which reduces the friction force and thus opens flexibly and easily.
4. The steel parts are made of stainless steel, and the rubber is made of food rubber, with high health quality.
5, the valve body diameter and pipe diameter equal diameter, open narrow and streamlined valve plate and fluid direction is the same, large flow and small resistance, no material accumulation.
6, the handle adopts the pull type and pull type, can withstand the larger operating torque, not easy to break.
7, the opening and closing range is 0~90 degrees, can be fixed in the position of every 15 degrees, with adjustable, and opening and closing fast, easy to operate.
8, the valve body is detachable connection, simple structure, easy maintenance.
9, the shape is light and beautiful, the surface is bright and not sticky, no burrs.
10, after strict strength and sealing test, to ensure the quality.
11, sampling for not less than 30000 times fatigue life test to ensure its service life.

Selection principle of hygienic manual thread butterfly valve

Sanitary butterfly valve (middle line soft seal butterfly valve) is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil and various acid and alkali and other thin-walled pipe roads requiring complete seal, zero gas test leakage, high life requirements, working temperature of 10ºC to 150ºC. Sanitary manual screw butterfly valve installation and maintenance should pay attention to the following matters: 1, in the installation, the valve disc to stop in the closed position.
2. The opening position should be determined according to the rotation Angle of the butterfly plate.
