14a – High Performance Wafer Style Butterfly Valve
The Pfeiffer BR14a double eccentric control butterfly valve is designed for general service applications up to the limits of the ANSI 150 pressure class rating. These general service applications include process events such as erosion, abrasion, and corrosion. The Pfeiffer BR14a design increases flow capacities but also reduces the pressure recovery factor making the design more susceptible to cavitation, flashing, and flow noise generation. The double eccentric design of this butterfly valve will reduce the breakaway torques required from the actuator.
The Pfeiffer BR14a control butterfly valve has standard options such as low and high temperature version. The Pfeiffer BR14a and BR14b 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.
Size: 3″ to 20″
ANSI Class: 150
Std. Materials: Carbon Steel, Stainless Steel
Temperature Range: 14 to 392oF (-10 to 200oC)
14b – High Performance Lugged Style Butterfly Valve
The Pfeiffer BR14b double eccentric control butterfly valve is designed for general service applications up to the limits of the ANSI 300 pressure class rating. These general service applications include process events such as erosion, abrasion, and corrosion. The Pfeiffer BR14b design increases flow capacities but also reduces the pressure recovery factor making the design more susceptible to cavitation, flashing, and flow noise generation. The double eccentric design of this butterfly valve will reduce the breakaway torques required from the actuator.
The Pfeiffer BR14b control butterfly valve has standard options such as low and high temperature version. The Pfeiffer BR14a and BR14b 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.
Size: 2″ to 20″
ANSI Class: 150 to 300
Std. Materials: Carbon Steel, Stainless Steel
Temperature Range: -76 to 662oF (-60 to 350oC)
14p – Butterfly Valve (PSA)
Pressure swing adsorption (PSA) is a method used to separate a gas from a gas mixture as well as to dry or clean gases. The purity and quantity of the gas to be extracted strongly depends on the control valves used in this process.
The control valves used in PSA applications must shut-off tightly, have short opening and closing times as well as a high level of operational reliability. SAMSON has developed the double-eccentric 14p butterfly control and shut-off valve to meet these challenging requirements.
Size: 3″ to 16″
ANSI Class: 150 to 300
Std. Materials: Carbon Steel, Stainless Steel
Temperature Range: -4 to 356oF (-20 to 180oC)
3331 – Centric Butterfly Control Valve
The Type 3331 centric control butterfly valve is designed for general service applications up to the limits of the ANSI 300 pressure class rating. These general service applications include process events such as erosion, abrasion, and corrosion. The Type 3331 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 of this butterfly valve will increase breakaway torques required from the actuator.
The Type 3331 control butterfly valve has several standard options such as swing through, step seated, angle seated, or low noise disc design, and temperature extensions. The Type 3331 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.
Size: 4″ to 16″
ANSI Class: 150 to 300
Std. Materials: Carbon Steel, Stainless Steel
Temperature Range: 14 to 752oF (-10 to 400oC)
LTR43 – Triple Offset Butterfly Valve
The Leusch LTR 43 triple offset butterfly valve is designed for general service applications up to the limits of the ANSI 2500 pressure class rating. These general service applications including process events such as erosion, abrasion, corrosion, cavitation, and flashing. The Leusch LTR 43 design increases flow capacities with the reduced pressure recovery factor compensated by special optional design features that address cavitation, flashing, and noise generation. The triple eccentric design of this butterfly valve will reduce the breakaway torques required from the actuator to nothing.
The Leusch LTR 43 control butterfly valve has standard options such as low and high temperature version, heating jacket, NACE materials, etc. The Leusch LTR 43 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.
