Description

Series SAV-BT Angle Seat Valve – Bronze NPT

Low Cost, Compact Design, For Use with Gases and Liquids

 

DWYER Series SAV-BT Angle Seat Valve pneumatic, externally piloted angle seat valve is operated by a single acting actuator with a mechanical spring for fail-safe operation. Constructed of bronze, 316 Stainless Steel, 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 DWYER Series SAV-BT Angle Seat Valve 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.

Product Applications

• Gas or liquid flow control

 

Features

• Integral heat sink protects Polyamide actuator
• Actuator can be rotated 360° for positioning pressure ports
