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.

Attention:

1.The valve is installed independent of the flow direction of the medium.

2. After the valve is assembled, the thread of the bolt/stem shall be greased to prevent corrosion and facilitate subsequent disassembly.

3. Do not use the valve for pipe pressure regulation, gate valves generally play the role of a switch, to achieve a good adjustment effect, it is recommended to choose a professional regulating valve, water erosion will affect the service life of the valve disc.

4Do not use valves with EDPM for gaseous fluids.


Installation instructions

1. Notice of water stop shall be issued before construction.

2. The water in the road should be avoided in the front row of construction.

3. Electricity for construction must be guaranteed.

4. It is strictly prohibited to use hand wheel, handle and transmission mechanism for hoisting and collision is strictly prohibited.

5. Lubricate the valve at least once a month if it is in frequent use.
