  • TypeOther
  • Reliable flow control for gas, oil or water service

1/2 Inch Gate Valve for Gas Oil Water

This 1/2 inch gate valve handles gas oil and water in residential and light commercial plumbing. The bronze body and solid bronze wedge resist corrosion across a range of fluid types. A rising stem with wheel handle gives clear visual indication of open or closed position. Union bonnet design allows straightforward inline maintenance without special tools.

Class 200 Steam Rating 400 psi Operating

The valve carries a Class 200 rating for steam service up to 200 psi and a maximum operating pressure of 400 psi for non steam media. Bronze seat and seal materials maintain tight shutoff under normal pressure and temperature cycles. Female NPT threads connect directly to standard pipe without adapters. The Cv of 17.6 supports adequate flow for typical half inch supply lines.

Sustained Pressure Service Bronze Construction

Under sustained load the all bronze construction resists creep and seat deformation better than mixed metal alternatives. The rising stem threads remain exposed to the media so regular cycling prevents seizing in mineral rich water. Union bonnet joints maintain seal integrity through thermal expansion and contraction cycles. This valve suits installations where frequent operation and long service intervals are expected.

Questions about this item

How do I install the 1/2 inch FNPT gate valve and what step is often missed?

Thread the valve onto the female NPT pipe using sealant on the male threads, then tighten with a wrench on the bronze body flats. The step often missed is orienting the rising stem so the handwheel has clearance to move up as the valve opens.

What maintenance or replacement will the valve need later?

The bronze seat, wedge and stem are integral to the body. Under normal water, oil or gas service the valve is maintenance-free. If leakage appears across the seat, the entire valve must be replaced because internal parts are not field-serviceable.

What limit appears first during sustained high-pressure use?

The Class 200 rating caps continuous steam pressure at 200 psi. In water or oil service the 400 psi cold working pressure is higher, so steam duty hits the pressure limit first.
