HSV High Pressure Solenoids & HLE10 High Pressure Logic Element (350 bar) Families Continue to Expand;

New HPRV08 High Pressure Pilot Proportional Pressure Relief Valve

 

HSV High Pressure Solenoid Valves:
The new Comatrol HSV High Pressure Solenoid Valve portfolio continues to grow. Last year, the 10, 12 and 16 size poppet-type designs were introduced to the market, along with 10 size 2-Way spool valves.   
The result of these releases added fourteen new HSV solenoid valves to the Comatrol portfolio. At I

Comatrol New Product Preview

FPE, Comatrol is launching nine new HSV valves and two new manual override options for these families.To complement the HSVP10, HSVP12 and HSVP16 size poppet-type for those higher flow, high pressure applications, the HSVP20 poppet design will be launched at IFPE, with a rated flow of 190 LPM [50 GPM]. As with the other HSVP poppet designs, 4 schematic designs are made available: Normally Open, Normally Closed, Normally Open w/ Reverse Free Flow and Normally Closed w/ Reverse Free Flow.

 

The 10 size spool-type (HSV10) valve line has also expanded and will be launched at IFPE. In addition to the already released 2-position, 2-way valves (HSV10-22-01 & HSV10-22-02), the portfolio has grown by 5 more valves: HSV10-23-01 and HSV10-23-02 which are 2-position, 3-way valves; HSV10-24-01 is a 2-position, 4-way valve; and HSV10-34-02 and HSV10-34-05 which are 3-position, 4-way valves. The key feature of all the HSV10 spool-type valves is their market-leading flow capacity, which in many cases is double the flow of their 210 bar counterpart. These valves were designed with high flow and low pressure drop to help minimize losses in the hydraulic circuit, thus conserving power and saving fuel on the vehicle.new products at IFPE

 

In addition to the new valves, new manual override options will be released at IFPE, which will be available on both the high pressure (HSV) and standard pressure (SV) product lines. The new Push-and-Twist (PAT) design allows the operator to push and then twist the manual override into a detented position. This allows for emergency actuation of the solenoid valve, holding the valve in the shifted position without requiring electrical signal to the coil. Repeat the push then twist operation to release from the shifted position. For 3-position, 4-way valves, a new Push-and-Pull (PAP) option will allow for emergency mechanical actuation in both directions. The valve is spring-centered, so when the operator releases the override, the valve goes back to the center position.

 

HLE10 High Pressure Logic Elements:

In addition to expanding high pressure solenoids, the HLE high pressure logic element line is continuing to expand. Comatrol designed the HLE10 models with the focus on delivering high performance in cost-effective valve designs with small space claims. These 350 bar (5075 psi) logic elements use a 10-3S cavity, which allows for higher flow than a standard 10-3 cavity.


comatrol high pressure logic elementsAdding to the recently launched HLE10-CPC (Normally Closed, Pilot-to-Close) and the HLE10-OPO (Normally Open, Pilot-to-Open) family, Comatrol is launching 4 new valves at IFPE. The HLE10-CVO is a high pressure logic element, normally closed, vent-to-open and features a rated flow of 80 LPM (21.1 US gal/min). This valve can be applied as a pilot operated relief valve (proportional or mechanical), pump unloading, pilot operated sequence valve or a selector valve, when used with other valves in the circuit.

Each of these three HLE10 schematics can be made available with an external screw adjustment and will be identified as HLEA (high pressure logic element, adjustable): HLEA10-CPC, HLEA10-CVO and HLEA10-OPO. The adjustability allows the operator to change the compensator setting of the logic element, ranging from 2.75 to 15.2 bar (40 to 220 psi). This is especially helpful when fine tuning the application, providing flexibility to the operator and allowing for machine optimization.

 

HPRV08-DAC High Pressure Proportional Relief ValveHPRV08-DAC High Pressure Proportional Relief Valve – Pilot Control:

Building upon Comatrol’s strength in both proportional relief valves (PRV10-POC, PRV12-POC) and fan drive control (RFDs), a new pilot control proportional valve family will be released at IFPE. These new direct-acting, normally closed valves come in high pressure (350 bar), HPRV08-DAC, and standard pressure (210 bar), PRV08-DAC, with flows of 1.2 LPM (0.32 GPM) and 2.1 LPM (0.55 GPM), respectively. These valves are perfect for piloting fan drive systems, where pressure control is the optimum solution. The valves can be combined with a logic element, like the HLE10-CVO, to create a high flow, high pressure proportional relief valve. ***
