Piloted relief valve
Our piloted relief valve :
Lower production losses with operating pressures close to the set pressure
Better opening/closing and tightness performances than those of spring relief valves
Type: 501
Functions – Piloted relief valve
♦ Safety device ; in-line or on vessel
Construction – Piloted relief valve
Construction materials: Carbon Steel (CS), Stainless Steel (SS), Duplex & Super Duplex, Inconel & Incoloy®, Titanium, Zirconium, Uranus® B6, Tantalum, Nickel, Hastelloy®, Monel
Construction methods: Fabricated (Welded), Cast, Solid
Uses – Piloted relief valve
Service conditions: High pressure, Low temperature, Corrosion, High viscosity
Types of fluids: Liquids, Liquids with solid particles – Slurry, Gas, High viscosity fluids
Applications: Fine chemicals, Petrochemicals, Nuclear and Naval / Submarine, Other applications
Features
♦ Immediate or modulating action
♦ Operating very close to the set pressure : no production/yield loss
♦ Not sensitive to counter pressure : easier line construction, bellows not required
♦ Shorter overall dimension than spring loaded safety valves
♦ Very good tightness : the more the fluid pressure increases, the more the disc presses the nozzle ; tightness up to set pressure
♦ Easy maintenance
♦ Short or long nozzle
♦ Compliance with PED 97/23/EC.
