Comatrol introduces the HSV high-pressure solenoid valve platform and HFCV10-RT high-pressure flow control. These developments are a continuation of Comatrol’s “Rhythm of Innovation,” with its strong focus on high-pressure development around standard NFPA cavities.
The HSV product line was specifically designed around standard NFPA cavities. Some competitive products require either non-NFPA cavities or a modified tool between standard and high-pressure. No tooling change is needed between standard (210 bar) and high pressure (350 bar) cavities to machine ports in the manifold, minimizing the number of tools to carry.
The new designs were optimized for high flow capacity, providing market-leading flow on many of the valves. Specifically, the HSV10-22 spool-type valves provide over 50% higher flow than comparable competitors.
This new high-pressure solenoid valve product introduction includes two-way poppet (HSVP) and spool (HSV) designs. All the new valves are available in both normally open and normally closed schematics, while the HSVP includes the reverse free-flow option. These valves are rated for pressures up to 350 bar (5075 psi) and have been qualified to the rigorous standards of NFPA T2.6.1. A range of four standard cavity sizes are available – 10-size spool and 10-, 12-, 16- and 20-size cavity poppet designs, summing to a total of eighteen (18) new valves. Flows range from 54 LPM to 190 LPM (14.3 to 50 US gal/min) at 7 bar pressure drop.
HFCV10-RT High-Pressure Flow Control – Adjustable and Compensated
Comatrol is also introducing the HFCV10-RT, which is a high-pressure (350 bar) cartridge valve. This 10-size restrictive-type flow control is a multi-functional valve that is fully adjustable and pressure compensated with reverse free-flow. The valve features fine adjustability for precise control of the flow, regardless of the load pressure. HFCV10-RT is ideal for meter-in and/or meter-out applications for accurate control of actuator speeds.
The HFCV10-RT maintains a constant flow rate out of Port 2 regardless of pressure variations at Port 2 or Port 1. An integral check valve allows unrestricted reverse free-flow from Port 2 to Port 1. The valve can be adjusted from closed to fully open (up to 11.4 LPM [3.0 US gal/min]) using the adjustment screw. Regulated flow ranges are available pre-set from the factory in 1 LPM increments between 1-11 LPM (0.26-3.0 US gal/min).
Make plans to stop by at BAUMA this week – Hall B4, Booth 313 (shared booth with Sauer-Danfoss) – to learn more and to see the new products on display.
