30/QR - QUICK PRESSURE-RELIEF VALVE - SERIES 300

The Dorot Series 300 Pressure-Sustaining (’30-QR’) activates by the pressure of the pipeline. The valve opens instantly when the pressure in the pipeline exceeds the safe level, thus relieving excessive pressure from the network. When the pressure returns to normal, the valve closes slowly, at an adjustable pace.

  • 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.

FLEL - Electrically-activated level control valve - 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 - Electric Float Controlled Valve - 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
