Comatrol Dramatically Expands High-Pressure (350 bar) Portfolio with New HSV Solenoid Valves and HFCV10-RT Flow Control at bauma 2013.
New HSV platform includes 18 new two-way solenoid cartridge valves using standard NFPA cavities for common tooling.
Munich, Germany – Comatrol, a global leader in the design, manufacture and sale of engineered hydraulic cartridge valves and hydraulic integrated circuits (HICs), today introduces the new 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.
“Over a year ago, we polled our customers to find out what they wanted for high-pressure solenoid valves and they told us high flow, low pressure drop, high shift reliability, environmentally robust coils − all with common cavities regardless of pressure rating,” said Darren Magner, Director Marketing & Product Development. “Our new HSV platform of solenoid valves gives our customers what they want, with a choice of 18 new two-way valves to choose from to best fit the application need.”
“Additional high-pressure products − including three-way, four-way and double-blocking 10-size solenoid valves and numerous mechanical cartridge valves − will be introduced throughout 2013,” Magner continues. “The new platform of product will create a strong portfolio of 350 bar cartridge valves to fulfill market demand for higher pressure applications.”
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 new HFCV10-RT, which is another 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).
High-Pressure – 350 bar
Higher pressures, such as 350 bar, allow machine designers to use smaller cylinders and motors on their vehicles, making them more compact and lighter weight. In response to market trends toward higher power density, Comatrol is introducing its new platform of high-pressure cartridge valves at the bauma 2013 exhibition.
In addition to high-power density, customers can apply these new high-pressure valves at lower pressure such as 210 bar and expect a longer component life as − compared to the more standard solenoid valves rated for 210 bar. There are many applications where servicing products are a challenge, so applying longer life components makes sense.
