德威爾Dwyer黃銅角座閥SAV-BTE3-NO_SAV-BTF3-NO
Save space while maintaining flow rates with the compact Series SAV-BT Angle Seat
Valve. The pneumatic, externally piloted angle seat valve is operated by a single acting
actuator with a mechanical spring for failsafe operation. Select from either normally closed
(NC) or normally open (NO) configurations. NO valves can be used to prevent waterhammer
on valve closure in liquid applications.
Constructed of bronze, 316 SS, and PTFE seals, the Series SAV-BT can be used in most gas,
liquid, and steam applications. Integral heat sinks dissipate heat protecting the Polyamide
actuator, ensuring longer life.
The Series SAV-BT can be mounted in any position. For added flexibility, the actuator
housing rotates 360 degrees for positioning of the pressure ports. Standard visual indicator
shows open or closed position.
