    Motorized Glass Control Valves : Application : Pickling Plant, Sector : Steel
    Marsh Introduces new range of Motorized Glass Valves for controlling flow of Acid in an Acid Regeneration Plant specially used in pickling Plant to recycle Waste Acid.

    The Package Mainly Consists of

    • Glass Valve
    • High Resolution Electrical Actuator
    • Accessories

    Brief Description

    Waste from pickling process which mainly consists of Hydrochloric Acid, Suspended Iron Particles & Water along with CNG & Air is feed to a reactor in controlled manner through motorized Glass Valve.This acid gets converted to gaseous form in the reactor which is again converted to acid in an absorption column.

    The Glass valve is made of Borosilicate glass and PTFE plugs. Glass valve allows visual checking to monitor flow of acid and see that crystallization does not take place. The valve has to be washed periodically with water to remove iron particles if any.

    Position Retransmission in 4-20mA for Valves / Dampers Position Transmitter Model : PPT 200
    APPLICATION

    The two wire transmitter model PPT 200 is an electronic instrument to convert resistance input to current output. The change in resistance derived from the field mounted potentiometer is given as an input to this instrument through two wires. A supply of 12 to 36 V DC is connected to the output terminals of the instrument. As the input resistance varies the current signal of 4-20 mA is generated in the supply wires which can be read by connecting an ammeter in series with the supply wires as shown in the connection diagram. The Zero and Span Setting potmeters are provided on this instrument by which accurate output values of 4 and 20 mA can be achieved.


    FEATURES
    • Two wire Transmitter
    • Uses state of art analog technology
    • Accepts wide supply voltage variations
    • Protection against reverse supply connections
    • Epoxy potting ensures excellent - protection against dust, moisture etc.
    • Customer setting - SPAN, ZERO -
    • easily accessible.
    • Note : SPAN and ZERO are interdependent
    TECHNICAL SPECIFICATIONS
    • Supply : 12 to 36 V DC
    • Input : 100 to 235
    • - Standard supply. Other values available on demand (Only two wires of potmeter to be used as input)
    • Output : 4 to 20 mA DC
    • Customer : Zero : 4mA Span : 20 mA
    • Linearity : ±1%


    Position Transmitter with linkages for Linear Application

    Technical Features Model PPT-200L

    This model has a reciprocating shaft, which can be coupled to any linear moving part so as to convert linear mechanical movement into an out put of 4-20 mA proportionately.

    The reciprocating shaft is coupled to the potentiometer and the potentiometer output is converted into 4-20mA thru position transmitter. All the items are housed in a box having proper sealing to make it weather proof. A suitable cable gland is provided for cable entry. Adjustable mechanical stoppers are provided on the reciprocating shaft to restrict the desired movement of the shaft.

    Industrial Boilers : Retrofitting existing High Pressure - Gate + Globe Valves
    Applications

    MARSH offers Electric Actuators for high pressure Globe & Gate Valves for ON / OFF and Regulating duty applications. They can be mounted directly on valves or the motion can be transmitted thru linkages depending on site conditions. The actuators are available with 230 / 110 VAC V AC 1 Phase or 415 V AC 3 phase motors to suit various valve sizes and operating pressures. The required standard and optional accessories are available to meet the specific process requirements. The service back up is also available for commissioning, to over-come initial troubles, and also to calibrate the unit with DCS / QCS compatibility.
