FUTURA shut-off and switching valves for ATEX environments up to 16 bar
FUTURA shut-off and switching valves shut off the air supply to a machine or a branch of the air line and exhaust the outlet downstream. You can then work on the machine or hose without pressure and without switching off the compressor.
The ball valve is operated manually and is locked with a padlock. The 3/2 valve switches electrically or by compressed air. Both come in four sizes with G 1/4" to 1" threads.
Which valve to choose
Ball valve with exhaust
Turn the knob through 90° and the supply is shut off and the outlet exhausted. In the closed position, you lock it with a padlock.
Electrically operated 3/2 valve
Normally closed: without current it shuts off the supply and exhausts the outlet. Coil 24 V DC, 115 V AC or 230 V AC.
Air-operated 3/2 valve
The same valve without a coil. It is switched by compressed air applied to the G 1/8" pilot port.
Locking during maintenance
Up to three padlocks can be hung on the ball valve. Everyone who works on the machine can lock it with their own.

How the ball valve works
The ball valve is a 3/2 shut-off valve. When you turn the knob through 90° clockwise, it shuts off the supply and exhausts the outlet downstream through a silencer. Without a silencer, the exhaust is very loud.
In the closed position, you pull out the locking plate and hang a padlock on it, up to three. The VHS20 padlock fits it.
After the supply is shut off, pressure can remain in the air line after the regulator. The valve with exhaust releases it, so you can work on the machine or hose without pressure.
How the 3/2 valve works
At rest, the valve is closed: supply 1 is shut off and outlet 2 is exhausted to 3. When you energise the coil or apply air to the pilot port, the valve connects the supply to the outlet. When switched off, a spring returns it.
The electrically operated valve is switched by a small pilot valve with coil. It is the same for all sizes and is also supplied separately: MCL-F24VDC, MCL-F230VAC and MCL-F115VAC. When replacing it, you screw it on together with its seal.
Potentially explosive atmospheres
Ball valves in sizes 1, 2 and 4 are mechanical devices with no ignition source of their own. According to the declaration regarding Directive 2014/34/EU, you can use them in zones 1 and 2 (gases IIA, IIB, IIC) and 21 and 22 (dust IIIA, IIIB), temperature class T4, under the conditions described for the entire FUTURA range. The declaration also lists the air-operated 3/2 valve in sizes 1, 2 and 4.
Electrically operated valves are not for use in potentially explosive atmospheres. Their pilot valve with coil would need its own design for explosive atmospheres. For the zones, therefore, choose the air-operated valve. No size 0 valve is for use there either.
Mounting
Mount the valves in the direction of the arrow on the body. You fix them to a wall with a mounting bracket and to other components of the same size with a connection kit, regardless of the thread.
The ball valve goes at the start of the unit, before the soft-start valve and the filter. With a lubricator, replace the silencers on the exhaust with filter silencers; oil mist is harmful to health.
Mounting parts by size
Neither the mounting bracket nor the connection kits are included; you choose them according to the valve size.
Accessories
- Spare pilot valve with coil for all sizes: MCL-F24VDC, MCL-F230VAC, MCL-F115VAC.
- Padlock VHS20. Padlocks VHS20-GSA and VHS20-GSB with the same order number open with one key.
Ventilek’s tip
Shutting off is not enough, the outlet must be exhausted. The FUTURA ball valve does both with one turn. When you then lock it, nobody can turn the air on until you have finished the work.
- What is the difference between a ball valve and a 3/2 valve?
- You operate the ball valve manually and it can be locked. The 3/2 valve switches electrically or by air, for example according to the machine control. Both exhaust the outlet after closing.
- Is the 3/2 valve open or closed at rest?
- Closed. Without current or without pilot air, it shuts off the supply and exhausts the outlet.
- What pressure does the electrically operated valve need?
- 2 to 10 bar at the inlet. The air-operated valve works from 2 to 16 bar.
- How many padlocks can be hung on the ball valve?
- Up to three. The VHS20 padlock fits it.
- Is the silencer included?
- Yes, on both the ball valve and the 3/2 valve it is in the exhaust thread. After a lubricator, replace it with a filter silencer.
- Are they suitable for potentially explosive atmospheres?
- Ball valves and air-operated valves in sizes 1, 2 and 4 are, according to the declaration regarding Directive 2014/34/EU. Electrically operated valves and size 0 are not.
Ball valves: inlet pressure 0–16 bar (size 0: 0–12 bar). 3/2 valves: electrically operated 2–10 bar, air-operated 2–16 bar. Working temperature −10 to +50 °C, lubricated or non-lubricated compressed air and neutral gases, coils IP 65.
