MOTORIZED BALL VALVES

Transcription

1 USE motorized valve has its peculiar use in interception and regulation of: zone heating systems glycol refrigeration systems systems that make use of alternative energy industrial systems in general using hot and cold fluids aqueducts automated systems in general Servocontrol All servocontrols are made for being directly installed on body valve with ISO F0 - F0 - F0 attachment. The -POIT -POIT servocontrol is available in the following versions: without relay (deviator) terminal neutral, phase on terminal open, deviated to terminal close (see wiring diagram) Each servo-control must be engaged using a single control with relay (switch) terminal neutral, terminal fixed phase, terminal control phase for opening (see wiring diagram) Several servo-controls may be engaged from a single control OTE Both versions have an O - OFF function (fully open or fully closed) -POIT version without relay may be set to intermediate positions using a suitable command. For modulating regulations refer to page. The servocontrol features: power to terminal - with fully open valve to be used as a remote control (with indication of opening, pump relay engagement etc) power to terminal with valve fully closed to be used as a remote control (closure indication) external components made of AISI 0 GVR and in OT brass for the use of the servo-control in particularly difficult conditions (PROTECTED TYPE ) Thanks to the high quality of this servo-control it is widely used in a variety of industrial fields for the regulation of fluids in the preservation field, as well as in the food sector and in glycol passage. manual opening on the servo-control to engage the valve in the event of an electrical power failure or emergency. an auxiliary opening micro-switch (clean ) which is electrically closed when the valve is open. optional use (opening complete indication, pump relay command, boiler command, PC signal etc). an auxiliary closure micro-switch (clean ) which is electrically closed when the valve is closed. optional use (closure completed indication, relay command, PC signal etc). For possible outdoor installations, if directly exposed at SU RAYS / BAD WEATHER, a SIMPE PREVIOUS FURTHER PROTECTIO is recommended.

The presence of phase on terminal permits the opening of the valve connected to the servocontrol, while the absence of phase on the same terminal determines its closure. (electrical auto-closure) OTE: In both cases, once opening has been undertaken, a power phase reaches terminal and the s of the auxiliary micros, if present, arrange themselves as indicated in the diagram (opening servocontrol), vice versa, once closure occurs, a power phase reaches terminal and the auxiliary micro s arrange themselves as shown in the relative diagram (closure servocontrol). Both the -POIT and -POIT servocontrols with relay remain in their original position, in the absence of electrical power supply.

OPE SERVOCOTRO COSED SERVOCOTRO WAY VERTICA Body valve In valves, the - way version available with two different spheres. In both cases, one hole is set axially to the common way,that is always opened. - WAY - HOE BODY VAVE. In the case of - hole ball, the second hole is located on one of the entrance ways while the third hole is positioned at right angles to the second hole: positioning towards the other entrance way requires 90 rotation. A feature of the hole shutter is that it is able to close one entrance way whilst beginning the opening of the next at the same time. For a short period, during the manoeuvre stage all the three ways inter-communicate. Once the operation is complete the valve returns to being a deviation valve to all intents and purpose, so the use of the - way - hole deviation valve is recommended when the three deviated ways can communicate between themselves, which is usually the case in heating systems. On the control rod there are two orthogonal millings that indicate which way communicates with the common way.

A feature of the hole shutter is that it is able to close one of the entrance ways beforee preparing the other for opening. The use of the - way - hole deviation valve is necessary when the deviated ways must never be in communication with each other. On the control rod there is an orthogonal milling that indicates which way communicates with the common way.

12 USE I ZOE HEATIG SYSTEMS Zone regulation is prescrived, in provided cases, by paraghraph no. of art. n. of D.P.R. /9 and regulated by art. paraghraphs no.,,, and. motorized valve can be used either in a O - OFF regulation or a modulating one. O -OFF REGUATIO: You execute it with a traditional thermostat, that can be a two-wire one, to be coupled to a servocontrol -POIT type, or with three-wire thermostat to be coupled with a servocontrol -POIT type. MODUATIG REGUATIO: To obtain high returns, new plant engineering requests a modulating regulation. Modulation action can be accomplished through two different kinds of servocontrol. MODUATIG THERMOSTAT WITH -WIRE COTRO (to be coupled to -POIT servocontrol with relay) and MODUATIG THERMOSTAT WITH -WIRE COTRO (to be coupled to -POIT servocontrol) which alternates opening and closing periods, which can be longer or shorter according to the difference between environmental temperature and set one. MODUATIG THERMOSTAT WITH -WIRE COTRO WITH STI I POSITIO OF THE VAVE (to be coupled to -POIT servocontrol) which determines a valve opening angle proportional to the difference between environmental temperature and set one. EXAMPE: With an environmental temperature of C and a set one of 0 C, opening angle would be of 90 correspondent to 00% of the fluid passage, when the environmental temperature will increase to 9 C, opening angle decreases to C correspondent to 0% of the fluid passage. The more the difference between environmental temperature and set one decreases the more the opening angle will decrease, until a difference of 0 C correspondent to closed valve. EECTRIC SCHEME OF STADARD TYPE SERVOCOTRO WITH MODUATIG USE FOR STI I POSITIO UI0 norm provides different efficienty for different ways for zone regulation. In particular, the following scheme, shows how to a modulating zone regulation correspond higher values of efficiency.
