    Needle valve

    Type RKS / RKV (ERHARD)
    Pressure: '10 / 16 / 25 / 40 / 63 / 100 / 160
    Nominal size: 100 - 2000
    ERHARD needle valves are innovative valves for the safe control of pressure stages and flow rates. The control valves type RKS/RKV are characterised above all by optimised flow behaviour and ultra-low pressure losses when fully open. The control range can extend up to 96%. There are different control inserts for each area of application in order to cover all operating cases: a vaned ring, slotted cylinder, pipe cylinder and other special inserts. The needle valves have a wide main seal in the cavitation-free space and also an additional shaft seal.

    Pinch valve aiRFlex®

    Type BS (RF Valves)
    Pressure: 4bar
    Nominal size: DN25 - DN350

    “The aiRFlex® pinch valve is designed for abrasive, corrosive and scaling sludge, liquids and powders.

    It is characterised by a full bore and it is interchangeable with most ball valves and diaphragm valves.

    Technical advantages:
    * Patented expansion folds prevent stretching. This reduces the stress on the tube and significantly increases the service
    life
    * No moving parts – tube is the only wear part.
    * Trouble-free operation – no blocking or clogging.
    * Increased service life of the tube, which does not stretch when closed.
    * Cost-effective solutions as no actuator is required.
    * The tube can be replaced without having to remove the valve from the line, thus guaranteeing low maintenance and operating costs.

    Operating pressure about 2 bar below
    the available factory air supply, up to
    max. 6 bar.
    The MONSYS monitoring system prevents
    unexpected emergency repairs.
