Pressure Sustain & Level Control

Pressure Sustain & Level Control

PS - Pressure sustaining valve - Series 300

The Dorot Series 300 Pressure-Sustaining Valve (’30-PS’) activates by the pressure of the pipeline. The valve maintains a steady, predetermined pressure in the network, upstream of its location. Should the upstream pressure exceed the required set-point, the valve opens, increasing network flow, thus reducing its upstream pressure. If upstream pressure falls below the required value, the valve closes drip-tight.

PS[R] - Pressure Sustaining/Relief Valve - Series 300

The Dorot Series 300 Pressure-Sustaining Relief Valve (’30-PS[R]’) activates by the pressure of the pipeline. The valve maintain a steady, predetermined pressure in the network, upstream of its location. Should the upstream pressure exceed the required set-point, the valve opens, increasing network flow, thus reducing its upstream pressure. Should upstream pressure falls below the required value, the valve closes drip-tight.

FLEL\PS-Electrically-activated level control valve\Pressure Sustaining - Series 300

Mounted on the tank / reservoir inlet, below or above the requested water level. Activated by An Electric Float pilot located in the tank / reservoir. It closes when the water rise to the requested maximal level, and opens fully when the water level drops to the preset minimal point. The differential between the water levels is adjustable.

FLEL\PS-ELECTRIC FLOAT CONTROLLED VALVE\Pressure Sustaining - Series 100

An electric sensor float, located in the tank/reservoir, sends a command to a solenoid controlled valve. The main valve will fully open when the solenoid activated and will close drip tight when the solenoid de-energized, thus enabling accurate and reliable differential level control. Optional Addition: Stepped Surge-Preventing Closure.

  • Accurate and repeatable differential level control
  • Low power electric activation
  • Fast response
  • Simple and reliable design
  • Easy installation and maintenance

FLDI1\FLDI2\PS - DIFFERENTIAL WATER-LEVEL CONTROL VALVE\Pressure Sustaining - SERIES 300

Water-level control valve- differential type Mounted on the tank / reservoir inlet, below or above the water level. It closes when the water rises to the requested maximal level, and opens when the water level drops to a preset minimal point. The levels difference is adjustable.

FLDI\PS - DIFFERENTIAL FLOAT CONTROLLED VALVE\Pressure Sustaining - SERIES 100

A float valve controls the main valve, closing it when the water reaches maximum level, and opening it when the water drops to its preset minimum level. The differential between the maximum and the minimum levels is adjustable. Optional Addition: Stepped Surge-Preventing Closure.

  • Accurate and repeatable differential level control
  • Adjustable differential
  • Fast response
  • Simple and reliable design
  • Easy installation and maintenance

AL\PS ALTITUDE AND BACK PRESSURE CONTROL VALVE\Pressure Sustaining - Series 300

Mounted on the inlet  of the tank / reservoir, below the water level. The valve is activated by the hydrostatic pressure of the water level. It closes when the water rise to the requested maximal level, and opens fully when the water level drops to the preset minimal point. The differential between the water levels is adjustable.

AL\PS - Altitute & back pressure control valve\Pressure Sustaining - Series 100

The main valve is controlled by a highly sensitive pilot, located outside the tank. The pilot opens or closes the valve in response to the static pressure of the water. The pilot allows for differential adjustments between the maximum and minimum level. Optional Addition: Stepped Surge-Preventing Closure.

  • Accurate and repeatable differential level control
  • Fast response
  • Easy access - no float is located in the tank/reservoir
  • Simple and reliable design
  • Easy installation and maintenance

AL\PS - ALTITUTE & BACK PRESSURE CONTROL VALVE\PRESSURE SUSTAINING - SERIES 500

The main valve is controlled by a highly sensitive pilot, located outside the tank. The pilot opens or closes the valve in response to the static pressure of the water. The pilot allows for differential adjustments between the maximum and minimum level.

Optional Addition: Surge-Preventing Closure (SP).

EC - ELECTRONICALLY - CONTROLLED VALVE (CONDOR) - SERIES 300

Dorot Series 300 Electronic Control Valve (’30-EC’) is an automatic, solenoid control valve, activated by the pressure of the pipeline. The valve controls by the versatile DOROT “ConDor” controller that enables all control functions, or combination of functions, at extreme accuracy. Can be controlled by any pulse- activating controller.

  • Better performance:

Regulates at a stable mode, regardless of valve-size, down to near-zero flow. Thus, eliminating the need for a special low flow plug-design (such as ‘V-port’) or a bypass valve.

‘Floating’, low-friction internal-trim design, guided by unique LPT® device.

  • Increased reliability:

All control ports are fitted with SST sleeves for preventing corrosion-blockage

Pre-shaped reinforced diaphragm – for easier assembly and improved longevity.

  • Reduced periodic inspection\maintenance labor:

The control-trim is fitted with a self-flushing, inline control-filter.

Easy in-situ adjustment and maintenance.

  • Versatility:

A standard and simple single-chamber valve design, provides smooth operation.  Conversion to a double chamber is a patented option.

EC-PLC CONTROLLED VALVE - SERIES 100

The valve is controlled by a PLC controller that enables local or remote control of various functions such as, time related operation, the batching of liquid, and conditional (automatically modified) control parameters, in various applications. A recommended option is using the Dorot “ConDor” controller that enables the selection from a vast range of pre-programmed control functions and their combinations.

 

  • Can perform any control function
  • Highly accurate and reliable electronic control • Low power actuation
  • Simple and reliable design
  • Controlled by Dorot ConDor valve controller or by a third party controller
