- Combination release valve for releasing CO2 one-way bottles with ½" UNF thread by different methods of actuation
- Piercing valve of series connection type, for interconnecting the CO2 outlet ports of several piercing valves. CO2 outlets are mechanically connected through integrated mounting block, hence no additional pipes required for the outlet end
- Valve inlets to be connected with pipes as required
- By interconnecting the CA-RA valves, up to 10 CO2 bottles within a group can be pierced at the same time. Using the valve blocks described in the following, it is also possible to combine several groups into one mechanical unit
- Minimum release pressure 8bar
- Maximum operating pressure 80bar
- Nominal bore (free cross section) of valve 4mm
- Nominal bore of piercing needle 2mm
- No tool required for tensioning the piercing needle
- Ambient temperature range: -20°C to +110°C
- CO2 bottles are not included in our supply (see valves, accessories)
The series CA-RA-PA valves are available in 4 versions that may be combined as necessary. Required for mounting: 2 threaded rods M4, 4 nuts M4 with washer
1. CA-RA-PA-A (head block):
- CO2 group outlet with 1/4" thread
- Intermediate or end block (see below) can be mounted on right-hand side
- For releasing, types HA / EA (manual / electrical release action) additionally require a CO2 pilot bottle
- For pipe connection of the valve, 1 male connector 1/4" (e.g. B1-8-1/4) and 1 male T-connector 1/8" (e.g. B9-6-1/8) will be required additionally
2. CA-RA-PA-M (intermediate block):
- Intermediate or end block (see below) can be mounted on right-hand side
- Including sealing ring for connection to the preceding block
- For pipe connection of the valve, 1 T-connector 1/8" (e.g. B7-6-1/8) will be required additionally
3. CA-RA-PA-E (end block):
- Head block of following group can be mounted on right-hand side
- Including sealing ring for connection to the preceding block
- For pipe connection of the valve, 1 male elbow union 1/8" (e.g. B5-6 1/8) will be required additionally
4. CA-RA-PA-S (single block):
- For releasing a single CO2 bottle. Piercing valve can be mechanically connected with groups of other piercing valves
- Head block or single block can be mounted on the right-hand side
- CO2 group outlet 1/4" thread
- For pipe connection of the valve, 1 male connector 1/4" (e.g. B1-8-1/4) and 1 male connector 1/8" (e.g. B5-6-1/8) will be required additionally
Example of interconnection:
1. CA-RA-PA-3-2: Combination release of series connection type, for pneumatically releasing:
3 CO2 - bottles in the 1st group and
2 CO2 - bottles in the 2nd group.
Valve is mounted as follows (CA-RA-...):
1st group: PA-A + PA-M + PA-E
2nd group: PA-A + PA-E.
