IOM FOR DYNATORQUE™ SPRING RETURN MANUAL OVERRIDE (SRD TYPE)

Override operates, but not full travel:

1. Never use excessive force. If the operator will not operate correctly, follow these steps.

2. Make certain that all compressed air has been exhausted from the pneumatic actuator. The actuator

must be vented on both sides of all pistons.

3. Check to ensure that the stop adjustment settings for the pneumatic actuator, valve, and override will

allow the desired amount of travel.

4. Be certain that nothing is physically preventing the valve from closing/opening. That is, make sure that

nothing is lodged in the valve trim (ball, plug, disc. etc.).

5. Check that no physical damage has occurred which might limit or prevent movement of the actuator.

Examples could be: a dented actuator cylinder, damaged drive coupling or hardware.

6. Check to ensure that no drive components have been deformed. All drive components and mounting

surfaces must be correctly aligned. Check all couplings for excessive wear or looseness and all bolts

are snug.

Still problems after performing above steps:

1. Cycle test the pneumatic actuator and override as an assembly apart from and not mounted to the

valve. Assuming these components cycle fully, the problem is probably the valve. Check the valve for

any obstructions. If no obstructions are visible call the valve manufacturer for further information.

2. If the pneumatic actuator and the override assembly do not appear to function properly, make sure that

the pneumatic actuator's spring is fully extended. Never remove or separate the pneumatic actuator

from the override without fully extending the spring. Separate the pneumatic actuator from the

override and cycle test separately. The problem component should be apparent at this time.

3. If the pneumatic actuator appears to be the problem, contact the manufacturer for further instructions. If

the override appears to be the problem please contact your local DYNATORQUE representative or the

factory.

Maintenance:

A. Storage: For best results, DYNATORQUE operators should be stored in a clean, dry area in their

original factory shipping containers. If operators are stored in high humidity areas, steps should

be taken to reduce the amount of moisture the units will be exposed to. Operator input shafts are

plated or stainless steel to prevent corrosion. If operators are being stored for a long period of

time, operator mounting surfaces should be lightly greased to prevent corrosion.

B. Maintenance: DYNATORQUE manual operators do not require periodic maintenance. They are,

for most applications, lubricated for life, with all components designed to have a life equal to or

exceeding the wear life of the operator gearing.
