TYPE 3500 INSTALLATION, OPERATION & MAINTENANCE MANUAL

1. WARNING

Users must strictly comply with the instructions and the use of proper function of an-

gle seat valves. DVC A/S will not be responsible for problems due to inappropriate use

of angle seat valves.

2. ATTENTION

Do not touch the valve body as it becomes hot during operation, which can

cause serious human injury.

3. AREAS OF USE

All our angle seat valves are made of 100% stainless steel, and can withstand medias

such as water, salt water, steam, chemicals, oil, crude oil and are suitable for use in

the textile industry and similar areas.

4. STORAGE OF VALVES

On receipt, check that the valve is in fully assembled condition. End caps on the valve

should be kept intact and removed only at the time of installation. Performance de-

pends on preventing damage to the seating surfaces.

Valves should be stored in a covered area. If a covered area is not available any wa-

ter proof covering material should be spread over the valves and the valves should be

kept on a wooden pallet at least 6" above the ground level.

Do not apply tar, paint, grease or any other material inside the valve or on the stem,

as this could interfere with the performance of the valve.

5. INSTALLATION

Before installation, remove all foreign matter in the pipline by flushing the line with

water or compressed air.

End connections of the valve should be carefully checked and cleaned before

installation. Taper threaded end fittings should not be overtightened. Valves should be

checked for proper alignment of gasket before tightening the flange joint.
