The Dorot Series 300 Pressure-Sustaining (’30-PS’) 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. If upstream pressure falls below the required value, the valve closes drip-tight.
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.
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.
A standard and simple single-chamber valve design, provides smooth operation. Conversion to a double chamber is a patented option.
