Type 355-1 Pneumatic Control Valve Type 355 Globe Valve Application Dump valve designed for use in high-pressure on/off applications in upstream oil and gas production. Valve size NPS 1 to 3 Pressure rating Class 600 to 1500 Class 1700 (intermediate rating, standard class) Temperatures 50 to +300 F ( 46 to +149 C) Type 355 Globe valve with Type 3571 Pneumatic Actuator, 7 to 116 in² effective diaphragm areas Valve body manufactured of A35 LCC Valve plug made of Stellite 6 (R30006) Tungsten carbide (only for compact version) Features Compact design the size of the valve has been optimized for installation where space requirements are tight Easy maintenance a threaded bonnet/body connection offers easier access to the trim without the need for assorted tools or removal of the valve body from the pipeline Travel limit adjustment by a threaded coupling Durable plug trim Standard trim material is Stellite 6 (R30006) NACE MR 0175/ISO 15156 compliance for use with sour gases and other corrosive media Environmentally friendly packing retaining a consistent seal due to the PTFE V-rings and the supporting spring. As the PTFE rings wear, the supporting Hastelloy spring adjusts to spread the V-rings wider, maintaining the seal longer, and in turn reducing the need for maintenance Interchangeable fail-safe action the fail-safe action can be changed without removing the valve from the actuator from air-to-open to air-to-close and vice versa Versatile actuator a supply pressure of 35 or 50 psi allows the entire range of differential pressures permitted in this pressure class to be safely controlled by the actuator, regardless of the flow direction (FTO, FTC) or the fail-safe action (air-to-open, air-to-close) Two-piece stem allowing the actuator to be removed prior to bonnet removal for easy maintenance Interchangeable flow direction (FTO, FTC) Fig. 1: Standard Version Type 355-1 Globe Valve Versions Standard version (Fig. 1) for temperatures ranging from 50 to +300 F and pressure rating Class 600 to 1500 and Class 1700 (ASME B16.34) Type 355-1 Standard globe valve (NPS 1 to 3) with Type 3571 Pneumatic Actuator and standard springs Type 355-1 Standard globe valve (NPS 1 to 3) with Type 3571 Pneumatic Actuator and reduced spring force when the air supply drops below 50 psi Compact version for temperatures ranging from 50 to +300 F and pressure rating Class 900 Type 355 Compact globe valve (NPS 1) with threaded ends and Type 3571 Pneumatic Actuator Type 355 Compact T-pattern valve (NPS 1) as globe or angle valve with threaded ends and Type 3571 Pneumatic Actuator Further versions Compact version with extended temperature range from 10 to +400 F ( 3 to +04 C) Edition January 017 Data Sheet T 883 EN
Principle of operation The process medium flows through the valve in the direction indicated by the arrow. The position of the valve plug determines the cross-sectional area between the seat and plug. Fail-safe positions Depending on how the compression springs are arranged in the actuator the control valve has two different fail-safe positions which become effective upon supply air failure: Actuator stem extends (fail-close, air to open): The actuator springs close the valve when the supply air fails. Actuator stem retracts (fail-open, air to close): The actuator springs open the valve when the supply air fails.
