Description

The Model 960 Spring Loaded Pressure Relief Valves are designed to handle higher pressure settings than standard dead weight loaded valves. These spring loaded Pressure Relief Valves are designed for pressures up to 1000 mbar for tanks with higher maximum allowable working pressures.

The model 960 was designed with features to exceed the performance of standard valves on the market.
Standard features include:
• The only dual guided [top and bottom) pallet for smoother valve stroke, less flutter and valve wear,
• Polyphenylene Sulfide (PPS), advanced composite thermoplastic material for seat and pallet providing superior resistance to corrosion, chemical attack, liquid and vapor adhesion, temperature extremes (-46° C to 260° C and sticking due to valve seat freeze.
• Fully field replaceable pallet and seat assemblies without need for special tools or complex procedures which eliminates the need to send out for rebuilding or total valve replacement. (Can be maintained by in house maintenance personnel)

The model 960 vent to atmosphere design maintains a tight seal until system pressure or vacuum exceed the set pressure of the valve. When overpressure occurs the spring loaded pallet lifts, breaking the seal between the seat and pallet, allowing vapors to pass through the valve orifice and relieving the pressure or vacuum buildup. The valve reseals upon relief and remains sealed.

Features & Benefits

• Advanced composite thermoplastic (PPS) materials for seat and trim provide superior resistance to corrosion, chemical attack, liquid and vapor adhesion, temperature extremes (-46° C to 260° C) and sticking due to valve seat freeze.
• Patented Saber Guide valve system provides for smooth valve stroke during operation and reduces valve wear.

• Exceeds the most stringent standards for allowable leakage and provides excellent set point accuracy.
• Fully field replaceable pallet and seat assemblies.
• Available in ANSI, DIN and JIS flanges.
