  • 286

    The 286 is a manually operated diaphragm valve of reduced dimensions and particularly compact structure, ideal for use in confined spaces.

    COMPACT DIAPHRAGM VALVE

    Connection system for solvent weld and threaded joints

    Extremely compact construction

    Internal operating components in metal totally isolated from the conveyed fluid

    Valve stem in STAINLESS steel

    Compressor with floating diaphragm support

    Easy to replace diaphragm seal

    Corrosion-proof internal components

    CDSA (Circular Diaphragm Sealing Angle) system offering the following advantages:- uniform distribution of shutter pressure on the diaphragm seal- reduction in the tightening torque of the screws fixing the actuator to

    the valve body- reduced mechanical stress on all valve components (actuator, body and

    diaphragm)- easy to clean valve interior- low risk of the accumulation of deposits, contamination or damage to the

    diaphragm due to crystallisation- operating torque reduction

    DN 12-15

    Technical specifications

    Construction Compact single wear diaphragm valve

    1 Handwheel in PA-GR, completely sealed, high mechanical strength with ergonomic grip for optimum manageability

    2 Integrated adjustable torque limiter designed to prevent excessive compression of the diaphragm and always guarantee a minimum fluid flow

    3 Optical position indicator supplied as standard

    4 Bonnet in PA-GR with STAINLESS steel nuts fully protected by plastic plugs to eliminate zones where impurities may accumulate. Internal circular and symmetrical diaphragm sealing area

    5 STAINLESS steel bolts, can also be inserted from above

    6 Threaded metal inserts for anchoring the valve

  • TECHNICAL DATA

    PRESSURE VARIATION ACCORDING TO TEMPERATUREFor water and non-hazardous fluids with regard to which the material is classified as CHEMICALLY RESISTANT. In other cases, a reduction of the nominal pressure PN is required (25 years with safety factor).

    KV100 FLoW COEFFICIENTThe Kv100 flow coefficient is the Q flow rate of litres per minute of water at a temperature of 20C that will generate p= 1 bar pressure drop at a certain valve position.

    The Kv100 values shown in the table are calculated with the valve completely open.

    The information in this leaflet is provided in good faith. No liability will be accepted concerning technical data that is not directly covered by recognised international standards. SED reserves the right to carry out any modification. Products must be installed and maintained by qualified personnel.
