Pressure Reducing Valve MODEL 30 PR UL
Pressure Reducing Valve, An automatic, pilot controlled, pressure reducing valve actuated by the pipeline pressure. The valve regulates to a steady, preset downstream pressure regardless of upstream pressure or flow rate fluctuations. In case of excessive downstream pressure, the valve closes drip tight.
FEATURES & BENEFITS
Simple field adjustable pressure setting; no special tools & no system downtime
Superior design featuring low pressure losses at high flow rates
Low lifelong maintenance costs due to unique frictionless internal trim design
High flows & working pressures (PN25/375psi)
Stable regulation near zero flow to maximum design flow
Regulates at low flow and high pressure differential without bypass or U/V port design
Out of the box fully assembled & tested valves
Extensive valve & trim materials selection and corrosion protection coating
Stainless Steel seat as standard
CERTIFICATION & COMPLIANCE

Operations
The 30-PRUL is a pilot-controlled, pressure reducing valve, actuated by the pipeline pressure.The valve accurately regulates to a steady, preset downstream pressure, down to near-zero flow rates, regardless of upstream pressure fluctuations and valve size. In case of excessive downstream pressure, the valve closes drip tight. The valve’s unique design eliminates the need for a special low flow plug design (such as V or U-ports), or the installation of additional smaller-sized bypass valves.
The valve’s low-friction internal trim design utilizes an LTP® (Linear Throttling Plug) guide and a pre-shaped reinforced diaphragm. The standard and simple single-chamber valve allows easier assembly, improved longevity and reduces periodic inspections and maintenance. When required, maintenance is easily done onsite and in-line. When planning operation and design, please consider the following:
• The valve should be suited to the maximum designed flow and allowed head loss.
• For added safety, installing a downstream pressure relief valve (30-PSUL, 77-PSUL, 44-PSUL or 108FCA) is highly recommended.
• Large pressure differentials may cause cavitation damage. Consult OCV for unique solutions if such conditions are expected
