CRANE Cast Steel Gate Valves
Crane Gate valves serve as efficient stop valves with flow in either direction. They are commonly used where a minimum pressure drop is important. Throttling is not recommended because partially open gate valves exhibit flow characteristics not conducive to accurate and consistent flow control. Also, the valves may be damaged by the high velocity across the seats. They function best fully open or fully closed.

Features
Flexible Wedge
- Compensates for deformation of body due to pipe stresses.
- Will not stick when valve is closed hot and allowed to cool.
Welded-in Seat Ring
- Seat ring is seal welded to eliminate leak path.
