Today, a batch of handle operated butterfly valves have been completed production, the specifications of this batch of butterfly valves is DN125, the working pressure is 1.6Mpa, the applicable medium is water, the applicable temperature is less than 80℃, the body material is made of ductile iron, with high strength and toughness, so this valve has good impact resistance and durability.

The working principle of the cast iron body butterfly valve is relatively simple, mainly composed of the valve body, valve disc, valve stem and handle. When the handle is rotated clockwise, the valve disc will be close to the center line of the valve body, and the valve will gradually close. When the handle is rotated counterclockwise, the valve disc will move away from the center line of the valve body and the valve will gradually open. By adjusting the rotation Angle of the handle, the opening degree of the valve can be precisely controlled, thus regulating the flow of fluid. In addition, the handle to clamp butterfly valve is also equipped with a sealing ring, when the valve is closed, the valve disc and the body form a tight seal to prevent fluid leakage.

The grip design makes the operation of wafer butterfly valve more convenient and intuitive. The user simply rotates the handle to open and close the valve without complicated operating steps or special tools. This design not only improves the work efficiency, but also reduces the difficulty of operation, making the maintenance and replacement of the valve easier.

The design of the manual butterfly valve also takes into account the ease of maintenance, and all components can be easily removed and replaced, greatly reducing the time and difficulty of maintenance.

Handle butterfly valve is suitable for water supply, drainage, fire and other fields of the pipeline system, especially in the need for frequent operation and maintenance occasions, compared with other similar products, the price of this handle pinch butterfly valve is more close to the people, cost-effective, is an ideal choice for many users.
