SZ45X non-rising stem gate valve characteritic:
1.the seal is designed with dustproof ring plus three "O" sealing ,realiable sealing on aceable.
2.both gate and aluminum bronze bearing are in inaid design good self lubrication,high strength and can have the aluminum bronze bearing replaced without need to replace the gate integrally,after a long time used.
3.rubber wrapped gate anti-corrosion good tihtness.
4.advance surface treatment,cpated with non-esign static powder,anti-corrosion,pollution-free ,can be used drinking water pipe
5.The body is designed without gate slot,the smooth passage will not get impurities filling up,more applicable for sewage working condition.
6.The integral seal works ralialy,for the high pressure seal,leaving zero leakage under 1.5 times nominal pressure and for the low pressure one,under 0.02mpa.
