1/2 in (15 mm) Bronze Gate Valve, Screwed | VBZG15
Available
This AAP bronze screwed gate valve has a bronze body, bonnet, wedge and stem, a ductile iron handwheel and female ISO 228 threads. It is supplied in 6 sizes from 1/2 in (15 mm) to 2 in (50 mm).
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. AAP says it is not recommended for flow regulation and should only be used fully open or fully closed.
AAP gives a maximum working temperature of 180 degrees C and a cold working pressure of 1,600 kPa (16 bar), with an ISO 228 thread, and lists the valve for water, oil, gas and irrigation (manufacturer-stated). The catalogue refers to this valve as the TM-107. ISO 228 is a parallel pipe thread, so match it to your pipework.

Selecting the right option
Choose the size to match your pipe thread. Use the valve fully open or fully closed rather than to throttle flow. AAP also lists a 2 in shouldered bronze gate valve with a T-lever, and a brass screwed version.
