Special Reminder:① If there is a fluid pressure difference condition, we recommend using a pilot type, which is beneficial for cost, product performance, and lifespan;

② When the user selects a special working pressure level or special working conditions, the corresponding power and parameters need to be reconfirmed. Please consult our company.
