    JMP Brake Valve Plus Retract Valve

    Here are JMP's new Brake Valves plus 1-Circuit Retract Valve.  The Proportional Brake Valve will activate most wheel brake designs in use today.  To work best your Brake servo should have at least 100 in.oz. of torque. We use a JR 8711HV servo for this. The Brake Valve requires about .5 inches of stroke to operate from zero to full system pressure. Lesser servos will work but will buzz more when applying maximum braking. As you increase the system pressure, it requires progressively more servo torque to deliver this pressure to the wheel brakes. 

    • The gear and door spools are our standard Hi-Flow design with the gear circuit using machined fittings and aluminum air line locknuts. Just set servo end points to push the spools from end stop to end stop to retract the gear or close the doors.

      We have several fitting sizes available for custom installations. The stock setup uses 1/8" air line fittings on the Brake Valve circuit. The Door circuit uses 1/8" fittings.

    JMP Brake Valve - Stand Alone Version

    The JMP Brake Valve is produced in two versions. The first is a stand alone design. The second version as part of the JMP Multi Spool Block Valve. The Brake Valve plus 1-Circuit Block Valve would normally be used for models with retract gear and brakes. The Brake Valve plus 2- Circuit Block Valve is for models that have brakes, retract gear and gear doors. Any of these valves can be mounted directly to the control board or used with our PCU-V2 frames which also include a manifold for the gear and door air lines.

    The size of the JMP Brake Valve is 2”x 7/8” x ½”. The height is designed to line up with a JR 8711HV servo. Just use our Zero-Flex grommets and the standard JR two side control arm.  Also available is a machined attach link to keep the install as compact as possible.

    Connect the brake air supply line to the “Air In” side elbow fitting and the “Air Out” fitting on the lower side of the valve to the wheel brakes. When the push rod is fully depressed, full system pressure will be delivered to the brakes. When the push rod is fully extended, the pressure to the wheel brakes is zero.

    • Standard 1/8" (1/16" i.d.) airline nipples.

    JMP 2-Circuit Fill Valve Panel for 4mm Air Line

    JMP 2-Circuit Fill Valve Panel for 4mm Air Line

     JMP’s new 2 circuit Fill Valve panel has two individual air circuits. Our new 1-way fill valve and high quality Pisco gauge are used for each circuit and securely mounted to a machined base. Normally, the circuits are for retract gear and brakes.

    On the rear side of the panel are two sets of hose barbs. One set is for the retract gear operating valve and retract gear air supply. The second set is for the brake valve and brake air supply. The Fill Valve panel also eliminates the need for T-fittings on two air circuits.

  4. JMP 2-Way Retract Hex Valve 4mm Fittings
    $63.00
    JMP 2-Way Retract Hex Valve 4mm Fittings

    JMP 2-Way Retract Hex Valve - 4mm Airline Version

    JMP’s new 2-way Hex Valve is now available. This servo controlled valve features six output fittings which will directly operate a common three air cylinder retract system.  The Hex Valve will often eliminate most or all of the T-fittings. The spool design has definite end stops which eliminates over travel. This is the highest flow retract cylinder operating valve available and can be ordered with hose barbs for 1/16” i.d. air line or 4mm air line.

    These Hex Valves are perfectly machined and carefully assembled with each one required to pass a “bubble tight” leak check.
