Manufacturer for Cast Iron Gate Valve - AZ Series Resilient seated NRS gate valve – TWS Valve Detail:


Description:

AZ Series Resilient seated NRS gate valve is a wedge gate valve and Non-rising stem type, and suitable for use with water and neutral liquids (sewage) . The non-rising stem design ensures the stem thread is adequately lubricated by the water passing through the valve.

Characteristic:

-On-line replacement of top seal: Easy installation and maintenance.
-Integral rubber-clad disc: The ductile iron frame work is thermal-clad integrally with high performance rubber. Ensuring tight seal and rust prevention.
-Integrated brass nut: By means of special casting process. the brass stem nut is integrated with the disc with secure connection, thus the products is safe and reliable.
-Flat-bottom seat: The sealing surface of the body is flat without hollow, avoiding any dirt deposit.

Application:

Water supply system, water treatment, sewage disposal, food processing, fire protection system, natural gas, liquefied gas system etc.
