- Minimum material required compared to similar sized control valves of different types
- Pneumatically actuated butterfly valve can be stroked extremely quickly
- Butterfly valve can be clamped between DIN and ANSI flanges
- Ideal basic soft seated centric butterfly design to meet tight shut-off requirements
PTFE/PFA Lined Rotary
3335 - Lined Butterfly Control Valve
Size: 2" to 12"
ANSI Class: 150
Std. Materials: EPDM/PTFE Lined Cast Iron
Temperature Range: 14 to 302oF (-10 to 150oC)
The Type 3335 centric lined butterfly control valve is designed for general service applications up to the limits of the ANSI 300 pressure class rating. The lined seat ring of the 3335 is made of either EPDM or PTFE which is ideal for tight sealing applications with extremely corrosive media found in chemical processes. The Type 3335 design increases flow capacities but also reduces the pressure recovery factor making the design more susceptible to cavitation, flashing, and flow noise generation. The centric design and lined seat ring of this butterfly valve will increase breakaway torques required from the actuator.
The Type 3335 can be assembled with a pneumatic, electric, hydraulic, or electro-hydraulic actuator also offered by the SAMSON group to complete the control valve construction. These control valves are designed according to the modular assembly principle, can be equipped with SAMSON GROUP actuators and valve accessories such as positioners, limit switches, and solenoid valves.
