Fig. 1: Type 3591-1 Control Valve

Fig. 2: Type 3591-5 Control Valve

Type 3591 Globe Valve operated with • Type 3271 Pneumatic Actuator (Type 3591-1 Control Valve)

for integral positioner attachment • Pneumatic piston actuator (Type 3591-5 Control Valve)

Special features: • Flanged-in seat for quick maintenance • Balanced to handle high differential pressures

Valve body made of • Cast steel • Cast stainless steel • High-temperature cast steel • Cold-resisting cast steel

Low-noise valve piston • Metal seal • High-performance metal seal (on request)

The control valves, designed according to the modular assembly principle, can be equipped with various accessories:Positioners, limit switches, solenoid valves and other accessories according to IEC 60534-6-1 and NAMUR recommendation (see Information Sheet u T 8350 EN).

ApplicationMaintenance-friendly cage valve for process engineering ap-plications with high industrial requirementsValve sizes NPS 10 to 32Pressure rating Class 150 to 900Temperatures –46 to 500 °C

2 T 8075-2 EN

Principle of operationThe medium flows through the valve in the direction indicated by the arrow. The position of the valve piston determines the cross-sectional area of the cage.Pressure balancing is mandatory.

Fail-safe actionDepending on how the compression springs are arranged in the pneumatic actuator, the valve has two fail-safe positions effective upon air supply failure.

Actuator stem extends (fail-close)The valve is closed upon air supply failure.

Actuator stem retracts (fail-open)The valve is opened upon air supply failure.

Note:Fig. 3 shows a configuration example.
