Crane Class 300 Outside Screw and Yoke
Crane Class 300 Outside Screw and Yoke SKU: CR_300
Description and Specs
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.

Crane gate valves offer the ultimate in dependable service for steam, air, gas, oil, oil vapor, and high pressure installations. All have straight through ports to assure minimum turbulence, erosion, and resistance to flow. They are available in a wide variety of trims.
