Multiple purpose safety valves for air / gas protection. Designed for durability, yet an economical choice for safety and relief applications.ASME and National Board certified for Section VIII as well as CRN Certifications. Choose for a variety of applications where mid-level capacity is required.

Series 69 is an industry standard liquid relief valve used for pressure relief and by-pass. Engineered and designed for heavy duty, industrial and commercial usages. A single piece bonnet to eliminate leakage while allowing for simple cleaning. Easy removable sealed hex-cap to adjust pressure. Series 69 Liquid Relief Valves are calibrated (set to pressure) based on a range of flow-rates (GPM) versus seat size and set pressure. Standard valve is set to pressure to achieve flow rate maximum and minimums within each set pressure range. See capacity chart for details. New (WR) wide range adjustable and available in 150 PSI increments.

Our Series 120, air / gas and steam pressure relief valve is designed for safety and pressure relief for light and medium capacity applications where a smaller sized valve is needed. The Series 120 valves have a higher capacity than our Series 130.
Many are manufactured to meet specific field and OEM applications. ASME and National Board certified for Section VIII as well as CRN Certifications. Essential for light- and medium-capacity situations where a smaller sized valve is needed. Not for use with liquid.

Our Series 130, air / gas and steam pressure relief valve is designed for safety and pressure relief for light and medium capacity applications where a smaller sized valve is needed. Many are manufactured to meet specific field and OEM applications. ASME and National Board certified for Section VIII as well as CRN Certifications. Essential for lower capacity situations where a smaller sized valve is needed.

Series 140 Safety Relief Valves are are designed for medium capacity applications where a smaller sized valve is needed. Essential for light and medium capacity situations where a smaller sized valve is required. Designed, tested and built for heavy-duty applications. Available in 2 Orifice sizes with a maximum 450 P.S.I. set pressure.
