Pneumatic Actuated Flanged Ball Valve 2-Way DN80 PN40 Stainless Steel Double acting

This pneumatically actuated 2-way DN 80 full bore flanged ball valve is made of stainless steel with Teflon (PTFE) sealings. The valve is suitable for water, oil, air, fuel and solvents up to a maximum pressure of 40 bar (580 psi), vacuum (max. -0.9 bar or -13 psi) and media temperatures from -20 to 180 °C (-4 to 356 °F). The actuator withstands temperatures up to 80 °C (176 °F), so for higher media temperatures the actuator should be cooled. The double acting actuator has an aluminum housing with aluminum covers. Delivers 98.6 Nm at 8 bars (control pressure 2.5-10 bar). ATEX certified for explosive environments (EX II 2GD c 110 °C). The actuator has G1/4 ports for the air supply and return. We recommend mounting a 1/4" Namur solenoid valve directly onto the actuator to control the air supply. Please note that 1/4 refers to the Namur size of the valve, not the port size. A limit switch box compliant to VDI/VDE 3854 can be mounted on top.

Pros:

• Ability to directly mount a Namur solenoid valve to reduce fittings and tubing
• Mechanical indicator on top shows the valve position
• ATEX certified for explosive environments (EX II 2GD c 110 °C)
• Unobstructed flow path thanks to the full bore design
• Easy installation and maintenance thanks to the standardized DN 80/PN 40 flange
• Lower investment cost than an electric version
• Fast opening/closing
• Suitable for aggressive media and high temperatures thanks to the high quality materials

Cons:

• Double acting utilizes more compressed air than single acting actuators
• The pneumatically actuated valve requires a compressed air system and a solenoid valve to control the air supply
• Energy consumption is higher than compared with electric actuators, but initial investment is lower

Series:

The PAL quarter turn pneumatic actuators allow you to control ball or butterfly valves with compressed air. They offer a reliable and robust solution to automate larger valves at a lower investment cost than electric actuators. They are mounted onto quarter turn valves with an ISO 5211 top flange (from F03 up to F12). With 8 different body sizes, they generate a torque range from 9.92 Nm to 901.8 Nm at 8 bar. Designed with a reliable aluminum rack and pinion rotational operation and designed to be either single acting (spring open or spring close) or double acting for increased control. These actuators are durable with an anodized aluminum housing and either an acetal resin (sizes 1-6) or aluminum (sizes 12-130) cover. The standard temperature range is -20 °C to 80 °C with an NBR seal, but an optional FKM seal is available for an increased maximum temperature of 120 °C (sizes 1-6) or 150 °C (sizes 12-130). All valves have a 1/4" Namur interface according to VDI/VDE 3845 with either G 1/8" or G 1/4" threads. The actuator is suitable for explosive environments thanks to the ATEX (EX II 2GD c 85 °C (size 12 or greater: 110 deg;C) certification.
