PRESSURE RELIEF MODEL 30 PS UL
Pressure Relief Valve, An automatic, pilot controlled, pressure relief valve, actuated by the pipeline pressure. The valve modulates to maintain a steady, predetermined pressure in the network. Should the upstream pressure exceed the required set point, the valve opens, releasing the excessive pressure. When the pressure falls below the set value, the valve closes drip tight.
FEATURES & BENEFITS
Simple ﬁeld adjustable pressure setting; no special tools or 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 and working pressures (PN25/375psi)
Maintains a steady preset system pressure, regardless of ﬂuctuating supply
Protects the system by accurately limiting maximum pressure
Out of the box fully assembled & tested valves
Extensive valve and trim materials selection and corrosion protection coating
Stainless Steel seat as standard
CERTIFICATION & COMPLIANCE
• ANSI FCI 70-2 Class VI seat leakage class
• UL listed under QXZQ category
• Lloyd’s type approval
Pump & Water Tanks
Fire Suppression Systems
Petrochemical, Oil & Gas Installations
Power Generation, Transformer & Transmission Plants
Onshore / Offshore
The 30-PSUL is a pilot controlled, pressure relief valve, actuated by the pipeline pressure. The valve accurately maintains a set pipeline pressure regardless of pump start and stop conditions. The relief pressure can easily be set and modified by use of the adjustment bolt on the pressure relief pilot’s cover.
When the system’s upstream pressure exceeds the required set point, the valve modulates to maintain a steady, predetermined pressure in the network. When pressure falls below the set value, the valve closes drip tight.
The CXPS pressure relief pilot, contains an integral and adjustable Stainless Steel needle valve which enables high pilot accuracy and control of the valve’s closing speed.
The valve’s low friction internal trim design utilizes an LTP® (Linear Throttling Plug) guide and a preshaped reinforced diaphragm. The standard and simple single chamber valve allows easy assembly, improved longevity and reduces periodic inspections and maintenance. When required, maintenance is easily done on site and inline.
