Frequently Asked Questions

Q: What pipe sizes are compatible with these brass gate valves?

A: These brass gate valves are available in seven female thread sizes: 1/8", 1/4", 3/8", 1/2", 3/4", 1", and 1-1/4" (corresponding to DN15, DN20, DN25, DN32, DN40, and DN50 metric sizes). Select the size that matches your existing pipe fitting for a secure, leak-free connection.

Q: Are these gate valves suitable for outdoor or garden water systems?

A: Yes. The solid brass construction makes these gate valves well suited for garden irrigation lines, outdoor water supply connections, and general household plumbing. They are rated for normal temperature water at medium pressure, making them ideal for most standard outdoor water applications.

Q: How do I install a brass female thread gate valve?

A: Installation is straightforward — simply thread the female-threaded valve directly onto a compatible male-threaded pipe or fitting. Use PTFE (plumber's) tape on the male threads to ensure a watertight seal. Turn the hand-wheel clockwise to close and counter-clockwise to open the valve.

Q: What is the difference between a gate valve and a ball valve?

A: A gate valve uses a rising or non-rising gate (wedge) to control flow, providing full-bore, unrestricted flow when fully open with minimal pressure drop. It is best used in fully open or fully closed positions rather than for throttling. Ball valves use a rotating ball and are better suited for quick shutoff applications.
