Type 37/38 Pneumatic Spring Diaphragm Actuator
The Masoneilan Type 37/38 pneumatic spring diaphragm actuator is a high thrust actuator for use with reciprocating or linear stem-motion control valves. It provides long stroke capability with optional construction to meet fail-safe action required by customers.
Features And Benefits
- Rugged design offers long-term reliable actuation and control performance
- Simple valve interface allows easy actuator assembly and disassembly from the control valve
- Low friction diaphragm design along with an external spring adjustment feature offers in-situ flexibility to meet changing conditions
- Single spring construction provides long stroke functionality covering a wide range of control valve applications
Common Applications
The Masoneilan Type 37/38 actuator is designed for use in globe control valve applications requiring longer strokes and higher thrust. It provides excellent throttling control performance and meets various fail-safe and linear thrust requirements using a single spring configuration.
Linear or reciprocating motion control valves
Pneumatically operated control systems
Low to high pressure drop applications
Mechanical spring fail-safe operation
Manual override to mechanically position valve
Mounts directly on control valve bonnet
Actuator stem connected directly to valve stem
