Description

The Model 951 (top mount) Pressure Relief Valve is an advanced design for vent to atmosphere applications. Utilizing the latest technologies, this relief valve provides protection against positive over pressure, prevents air intake, evaporative loss of product and helps contain odorous and potentially hazardous vapors.

The Pressure Relief Valve model 851 was designed with features to exceed the performance of standard valves on the market. Unmatched features include Saber Guide valve system and advanced composite PPS seat and trim for superior performance.

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)
* Also available in spring loaded design (Model 961 ).
