need to be changed.

Contact us for details.

Low pressure loss type of production and I are available. Contact us for

details.

Pressure loss of liquid, please contact.

☆ 1 : It becomes the pressure loss during the valve fully open

☆ 2 : If body wetted parts materials made of PVC, can not be produced

more than 0.12 ∼ 1.2L/min.
