G1-1/2 inch L-bore 3-Way PVC Pneumatic Ball Valve Spring Open PTFE

This pneumatically controlled 3-way PVC ball valve (L-bore) allows for an increase in automation to your system compared to a manually controlled valve. The ball valve has a 40 mm diameter and is suitable for contaminated water or corrosive media, such as chloride solutions (seawater or swimming pools) from -20 to 80 °C (-4 to 176 °F). The valve is also resistant to many salt solutions, acids and bases and solvents. The pneumatic actuator is capable of creating 28 Nm of torque at 8 bar, but it has a control pressure window of 6 – 10 bar. The ball valve has G ports to connect it to the application's piping/hosing. The actuator is spring open with a reliable aluminium rack-and-pinion rotational operation. The actuator has an anodized aluminum housing and an aluminum cover, while the ball valve has a PVC housing and PTFE/EPDM seals. The maximum media pressure is 10 bar (145 psi). 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. Also, a position control or limit switch box can be mounted on the top of the actuator according to VDI/VDE 3845. The actuator is mounted on the ball valve via the ISO 5211 F05 flange (11 mm square size). FKM available on request.

Pros:

• Ability to directly mount a Namur solenoid valve to reduce fittings and tubing
• Mechanical indicator on top shows the valve position
• ATEX (II 2G Ex d C) certified for explosive environments
• Lower investment cost than an electric version
• Fast opening/closing
• Single acting conserves compressed air and the valve will return to initial position in case of air or power loss.
• Can be equipped with a limit switch box

Cons:

• Single acting gives less control than double acting actuators
• Energy consumption is higher compared to the equivalent electric actuation, but the initial investment is lower

series

BL3PA

The BL3PA series PVC ball valves are reliable 3-way ball valves with an L-bore or T-bore. The ports range from G 1/2 inch to G 2 inch and from 20 mm to 63 mm solvent sockets. The housing is made of PVC, the ball is made of PVC-C and the valve seats are made of PTFE/EPDM or FKM/EPDM. The valves are suitable for contaminated water or corrosive media, such as chloride solutions (seawater or swimming pools) and resistant to many salt solutions, acids and bases and solvents up to a maxiumum pressure of 10 bar (145 psi). Suitable for temperatures between -20 and 80 ׄ°C (-4 to 176 °F). Ball valves from the BL3PA series all have an ISO 5211 top flange (from F03 to max. F07) which makes the mounting of an actuator possible.

PAL

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 (II 2G Ex d C) certification.
