AAP Resilient Seat Gate Valve, 6"

This AAP clockwise resilient seat gate valve has a ductile iron body and socket ends. It is supplied in 6 sizes from 4" (100mm) to 12" (300mm).

A resilient seat gate valve closes with a rubber-covered wedge that seals against the body, which keeps the bore free of the pockets a metal-seated valve has and is why it is widely used in water mains. A wedge gate valve moves a wedge-shaped gate between two body seats using a spindle, so when it is fully open the fluid has a straight, uninterrupted passage with very little pressure drop. It is not recommended for flow regulation and should only be used fully open or fully closed. The maximum working temperature is 40°C and the cold working pressure is 1,600 kPa (16 bar), with the design to AS 2638.2, flange drilling to AS 4087 (Table C) and AS 2129 (Table E), socket ends to AS 2280 and coating thickness to AS 4158. DN50 and DN65 are not covered by AS 2638.2, and the 2" and 2-1/2" Table C valves are marked as not certified. The body and bonnet are epoxy coated ductile iron, the wedge is ductile iron with bonded rubber, the stem is 431 stainless steel and the seals are EPDM.

Choosing the right option

Choose the size and the operating direction your network uses, clockwise (red cap) or anticlockwise (white cap), and the flange table that matches your pipework. Valves are operated with a key or handle, which are separate items along with stem extensions.
