2.0 The Difference Between OS&Y Gate Valves and NRS Gate Valves
Difference in Working Principle Between NRS Gate Valve and OS&Y Gate Valves In a non-rising flange gate valve, the lifting screw only rotates without moving up or down, and the only part visible is a rod. Its nut is fixed on the valve disc, and the valve disc is lifted by rotating the screw,...Read more -
1.0 The Difference Between OS&Y Gate Valves and NRS Gate Valves
Commonly seen in gate valves are the rising stem gate valve and the non-rising stem gate valve, which share some similarities, that is: (1) Gate valves seal through the contact between the valve seat and the valve disc. (2) Both types of gate valves have a disc as the opening and closing element,...Read more -
