Special Reminder:
① If there is a fluid pressure difference condition, we recommend using a pilot type, which is beneficial for product performance and lifespan;
② When designing the control scheme, try to choose a normally closed type. This valve is suitable for continuous operation. If a normally open type is necessary, please consult us.
