Spring Return Ball Valve
The Dead man Lever Type Valve The three-piece spring automatic reset ball valve is a relatively new type of ball valve. The valve seat adopts elastic sealing structure, which is reliable and easy to open and close. The valve stem adopts downloading structure with reverse seal, and the valve stem will not be washed out when the valve chamber is abnormally pressurized. The advantage of spring automatic reset ball valve is that it can reset automatically without manual closure, which not only saves time and labor, but also avoids the loss of medium flow. The main characteristics of spring automatic reset ball valves are small fluid resistance, simple structure, small size, light weight, compact and reliable, easy operation, convenient maintenance, three-piece ball valves are widely used in petroleum, chemical industry, urban water supply and drainage and other strict cut-off conditions. The three-piece spring automatic reset ball valve is composed of three-piece ball valve and spring handle. The main principle of spring automatic reset ball valve is that a spring handle is installed on the basis of three-piece ball valve. Its working principle is to reset automatically by triangular lever and spring compression spring. This product is also called spring automatic return ball valve, spring automatic close ball valve, spring automatic return ball valve, spring automatic return ball valve, etc. Their products all have the same function, but they are called differently.

Definition of two-piece spring automatic reset ball valve:
1. Manual quick automatic reset to avoid manual operation errors, no one closes after opening, resulting in media loss and other major accidents.
2. It is safe and reliable. It can be equipped with padlock to ensure that the valve is opened and the valve is closed by people. The safety performance is greatly improved.
3. All kinds of 90 degree rotary ball valves with ISO5211 platform can be equipped with three-piece, two-piece and flanged ball valves with size of 1/4"-4", which are widely used in petroleum, chemical, food, sanitation and other industries.
4. Replace the torsion spring with the simplest compression spring, and adjust the size of the torque without replacing the spring.
5. It has a wide range of applications. All rotary valves equipped with automatic reset handles can meet the requirements of automatic reset function.
