- Stable operation is easy to achieve by adjusting the needle valve opening to match the usage conditions.
- In addition, it responds quickly to pressure changes and closes rapidly when the pump stops.
- Moreover, the main valve and pilot valve can be easily disassembled.
- As a result, maintenance tasks such as adjustment, repair, and parts replacement are simple.
- Furthermore, the lift-limiting mechanism helps control and limit overflow.
