easy-e Valves

The easy-e Valve Family

easy-e valves are rugged, single-port globe, angle,
and reverse-acting (push-down-to-open) valves
designed for many varied applications. Although
there are many variations available, internal trim
parts are interchangeable for many different trims,
and maintenance procedures are similar. These
features reduce spare parts inventory and simplify
maintenance training.

Interchangeable Trim Sizes . . . Many easy-e
valves feature interchangeable, restricted-capacity
and full-size trims to meet variable flow demands.

657 and 667 Pneumatic Diaphragm Actuators . . .

Rugged, heavy-duty spring-return actuators. These
actuators are available with a variety of instrument
accessories, handwheels, and adjustable travel
stops. They can be used for on-off or throttling
operation with or without a valve positioner.

3025 Diaphragm Actuators . . . Spring-opposed
diaphragm actuators. Suitable for travels up to 200
mm (8 inches). Specified as either direct or reverse
acting, actuator action can be easily changed on site
without need of additional parts. They can be used
for on-off or throttling operation of automatic control
valves.

Piston Actuators . . .
actuators for high thrust requirements.

J 585C size 25 through 130

J 585CLS

(long stroke) piston actuators feature high thrust and
long travels for very large valves.

Accessories

FIELDVUE Digital Valve Controller . . . The

controller is available mounted on actuators.

Positioners and Transducers . . . Pneumatic
positioners and electro-pneumatic positioners and
transducers can be provided with these valves.

Position Transducers, Solenoid Valves, Limit
Switches, and Controllers . . . Also available.

packing at low process

temperatures, an extension

prevent valve stem frost.

Frost can damage the
