Actuators

Spring-Diaphragm
Actuators for quarter turn and reciprocating applications. Depending on the size, capable of direct operation with 3-15 psig or a minimum air supply pressure of 40 psig.

Piston
Actuators for quarter turn and reciprocating applications. Operate within supply pressure ranges of 40-150 psig. Available in either double acting or spring return versions.

Electraulic
REXA Electraulic actuators use a 120 VAC supply and have high repeatability, low hysteresis, and fast response time. These units are designed for continuous throttling with exact responses and can be used reliably for high cycle applications as there are few moving parts. The electric motor runs a hydraulic compressor which actuates the valve and this is done within a compact and rugged actuator.

Solenoid Valves

Available in 3-way and 4-way constructions for normally open, normally closed or universal operation. Namur mounting style available for direct mounting to actuators.

Limit Switches

Rotary
Solid state, proximity and mechanical switches available. Also available to communicate on bus networks such as ASi, Modbus, Profibus and Foundation Fieldbus.

Reciprocating
A solid state sensor for point sensing applications in corrosive and hazardous environments.
Also available is the Prism series limit switches for mounting onto diaphragm valves.

Other Accessories

Other valve automation accessories, such as filter regulators and speed control components are available.
