Cast Steel Gate Valves

inquiry
  • TECHNICAL DATA
  • INFO FORM
Criangle cast carbon steel (WCB) 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.
