2. General product information Description The 'C' series is a range of carbon steel (CE43), alloy steel (CE83) or stainless steel (CE63) two port, cage trim, control valves conforming to ANSI B 16.34 and ASME VIII standards. The valves are available in sizes 1" to 8" (DN25 to DN200), with ANSI and PN flange connections. When used in conjunction with a pneumatic linear actuator the 'C' series valve will provide characterised modulating or on / off control.

Page 9 4. Maintenance Note: Before actioning any maintenance, observe the 'Safety information' in Section 1. General Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance frequency depends on the severity of service conditions. This Section gives instructions for packing lubrication, packing maintenance, trim maintenance, and bellows seal replacement.
Page 10 Procedure for renewing chevron gland seals For spring-loaded single PTFE chevron gland seals, the gland spring (10) maintains a sealing force on the packing. If leakage is noted around the stuffing box bush (18) check to be sure the shoulder on the bush is touching the bonnet. If the shoulder is not touching the bonnet, tighten the stuffing box nuts (16), until the shoulder is against the bonnet.

Page 12 Procedure for renewing graphite gland seals If there is undesirable packing leakage first try to limit the leakage and establish a stem seal by tightening the stuffing box nuts (16). Note: If the packing is relatively new and tight on the stem, and if tightening the stuffing box nuts does not stop the leakage, it is possible that the valve stem is worn or damaged so that a seal cannot be made.
