These updates include the re-introduction of the VCB product line, which has the unique feature of piloting on port 1 (nose of the valve), allowing for a slimmer dual counterbalance design. Additionally, Comatrol is releasing an updated 20 size counterbalance valve, the CB20-HV, capable of 266 LPM (70 US gal/min). Pre-engineered dual-counterbalance HICs of each valve are also being introduced for the first time with this launch.

The VCB counterbalance product line includes four valves: VCB06-EN (hydraulic vent, 06 size metric, 60 LPM [16 US gpm]), VCB06-CN (atmospheric vent, 06 size metric, 60 LPM [16 US gpm]), VCB12-EN (hydraulic vent, 12 size metric, 140 LPM [37 US gpm]) and VCB12-CN (atmospheric vent, 12 size metric, 140 LPM [37 US gpm]). Each of these VCB products has the distinct function of piloting on port 1, at the nose of the valve. This is in contrast to most counterbalance valves in the market that pilot on port 3, which is located closer to the thread. Compared to the pilot at port 3 design, the VCB’s pilot at port 1 eliminates the need for cross- drilling when creating a dual counterbalance system in an HIC. Each of the VCBs is rated at 350 bar (5075 psi).

The new VCB-DL dual counterbalance, pre-engineered catalog HICs include the VCB06-EN-DL (hydraulic vent, 06 size metric), VCB06-CN-DL (atmospheric vent, 06 size metric), VCB12-EN-DL (hydraulic vent, 12 size metric) and VCB12-CN-DL (atmospheric vent, 12 size metric). In addition to decreasing design and machining time, the dual-counterbalance HIC allows for all four ports to be on one plane, making hydraulic piping connections easier for mounting on or near a cylinder.

Comatrol’s updated 20 size counterbalance valve, the CB20-HV, is Comatrol’s largest counterbalance valve and is a hydraulically vented cartridge capable of 266 LPM (70 US gal/min). The CB20-HV provides high flow capacity for those applications needing controlled load-holding for large cylinders and motors. The DCB20-HV is the new 20-size pre-engineered dual counterbalance HIC, available in both aluminum and steel bodies. The CB20-HV and DCB20-HV are rated at 350 bar (5075 psi).

Comatrol’s counterbalance portfolio now includes 9 cartridge valves with a flow range extending from 20 LPM (5 US gpm) to 266 LPM (70 US gal/min) at 22 bar (319 psi) pressure drop. Each valve is capable of 350 bar (5075 psi) and now available in pre-engineered dual counterbalance HICs. Multiple pressure settings and pilot ratios are available to match the right valve and settings to specific circuit requirements. Comatrol counterbalance valves incorporate a high power to weight density, maximizing performance in a small space claim.
