spring return ball valve Description
Spring Return Ball Valve is a ball valve that uses a spring mechanism to achieve automatic closing or opening functions. It is often used in scenarios that require quick cutoff, emergency closing or frequent operation.
According to the reset method, it can be divided into closed reset (automatically closed after releasing the handle) and open reset (remaining open under specific working conditions).
Core structure
Valve body and valve cover: The material is mostly cast steel, stainless steel or corrosion-resistant alloy, suitable for high pressure (Class300), high temperature (450℃) and corrosive media; Ball and seal: The ball is made of 316 stainless steel or hard alloy, and the sealing surface is PTFE or metal hard seal to ensure high sealing; Spring mechanism: Through the triangular lever type or unilateral compression spring design, automatic reset after the handle is released is achieved.

spring return ball valve
Features
Automatic reset and fast response
No external power is required, the valve can be automatically closed or opened by spring, and the response time can be as short as 0.05 seconds, which is suitable for emergency shut-off scenarios;
The handle is easy to operate, and it can be opened and closed by rotating 90°.
High sealing and durability
PTFE sealing ring achieves zero leakage at room temperature, and metal hard seal is resistant to high temperature and particle wear;
The modular design supports fast maintenance, and the service life can reach tens of thousands of opening and closing cycles.
Wide adaptability
Adaptable to connection methods such as threads (such as TQ11F type 2) and flanges (such as TQ41F type 1) to meet different pipeline requirements;
Can handle water, oil, steam, corrosive liquids and particle-containing media (such as sewage, pulp)
