12 Inch Gate Valve

Product Introduction

Product Description

The 12 inch gate valve can also be called 300mm gate valve or gate valve dn300, which is often used in boiler installations and steam services, and is a very common gate valve size.

12 inch gate valve controls the media’s flow by lifting the gate (open) and lowering the gate (closed). A gate valve’s distinct feature is the straight-through unobstructed passageway, which induces minimal pressure loss over the valve. The unobstructed bore of a gate valve also allows for a pig’s passage in cleaning pipe procedures, unlike butterfly valves. Gate valves are available in many options, including various sizes, materials, temperature and pressure ratings, and gate and bonnet designs.
