Design features

Gland: there are 5 O-rings in the upper seal. The two O-rings on the pressure ring can be replaced under the open state of the disc. Copper thrust ring, increase sealing and service life. Water line design, increase the sealing, can be made according to customer requirements.

Disc: linear sealing, reduce operating torque, improve sealing performance; The A point of the valve disc, the company combined with years of practical experience, innovative design of the waist of the valve disc A point, plane to avoid excessive contact with the valve body under strong pressure, so as to avoid the conventional valve is prone to encounter the valve disc damage, iron exposure, rust and other problems, greatly improving the service life of the valve.
