G1/2'' 2-Way Brass Pneumatic Ball Valve Spring Closed - BL2BA

bl2ba-012-PC-002
Tameson

This pneumatically actuated 2-way ball valve with G 1/2" threads has a nominal diameter of 15 mm (Kv-value 20 m3). The spring closed actuator has an aluminum housing and either an acetal resin cover. Delivers 6.3 Nm at 8 bar. Connect an air hose utilizing the G 1/8" connection point or mount a 1/4" Namur solenoid valve directly on the actuator. The ball valve has a brass housing and a PTFE seal. Suitable for media from -20°C to 160°C and a max media pressure of 40 bar. ATEX (EX II 2GD c) certified for explosive environments.

Description

This pneumatically controlled 2-way ball valve allows for an increase in automation to your system compared to a manually controlled valve. The ball valve has a 15 mm diameter and is suitable for liquids and gases from -20 to 160°C. The pneumatic actuator is capable of creating 6.3 Nm of torque at 8 bar, but it has a control pressure window of 6 – 10 bar. The ball valve has G 1/2" threads to connect it to the piping/hosing carrying the media and the Kv value is 20 m3. The actuator is spring closed with a reliable aluminium rack-and-pinion rotational operation. The actuator has an anodized aluminum housing and an acetal resin cover, while the ball valve has a brass housing and a PTFE seal. The maximum media pressure is 40 bar. Namur VDI/VDE 3845 connection points are already on the actuator to mount a 1/4" Namur solenoid valve directly onto the actuator or connect an air hose utilizing the G 1/8".  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 F03 flange (9 mm). The assembly is ATEX certified (EX II 2GD c) and may therefore be used in potentially explosive environments.

Pros:

  • Ability to directly mount a Namur solenoid valve to reduce fittings and tubing.
  • Mechanical indicator on top shows the valve position.
  • ATEX (EX II 2GD 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.
  • It 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.

palc-002-03-09 series

BL2BA

The BL2BA series ball valves are reliable 2-way ball valves with a brass housing. The ball is made of hard chromed brass and the valve seats are made of PTFE/FKM. The valve is suitable for various media, such as water, oil or air up to a maximum of 20 - 40 bar depending on the diameter size (G 1/4" - G 4"). Suitable for temperatures between -20 and 160 degrees Celsius. For corrosive or aggresive media, a valve made of PVC or stainless steel is better suited. Ball valves from the BL2BA 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 (EX II 2GD c) certification.
