Valves & Actuation

This solid, proven design is well suited for a variety of chemical, industrial and irrigation applications. Spears Gate Valves are feature-packed with multiple end connector options. Individual special features are found in each size range 1/2” through 2”, 2-1/2” and 3”, and in the full-featured Heavy Industrial 4” valve. Spears computer-engineered, heavy-bodied PVC or CPVC construction adds extra strength with superior chemical and corrosion resistance. 1/2” through 2” sizes are rated for 200 psi @ 73°F, 2-1/2” and 3” sizes are rated for 150 psi @ 73°F and 4” heavy-duty industrial gate valve is rated for 235 psi @ 73°F.

Features

PVC Utility Swing Check Valves are designed for horizontal installations, but may be installed in up-flow vertical position. Check valves must be installed with the valve’s FLOW arrow pointing in the direction of the flow. Flow velocity should not exceed 5 feet per second.

• Pressure Rating - 150 psi @ 73°F     • Maximum Service Temperature - 140°F     • EPDM seal for positive sealing
• Flow velocity < 5 ft./sec.

PVC Utility Spring-Assisted Check Valves are designed for horizontal installations, but may be installed in up-flow vertical position. Check valves must be installed with the valve’s FLOW arrow pointing in the direction of the flow. Flow velocity should not exceed 5 feet per second. Excellent for Pool and Spa, OEM and General Purpose applications.

• Pressure Rating - 150 psi @ 73°F     • Maximum Service Temperature - 140°F (Temperature/Pressure De-Ratings Apply)
• EPDM seal for positive sealing      • Stainless steel spring assisted (non-adjustable)
• Minimum opening pressure is 0.5 psi.
