Angle and Needle Valves

Hayward Angle Valves are used in tight spaces where a 90° change in flow direction is needed and there is insufficient room for extra fittings. Since they are globe type valves, they are ideal for sampling and for throttling applications. Hayward Angle Valves use precision-machined, fine-pitch threaded stems that allow for precise flow control down to shutoff. The 1/4" size valve has integrally molded-in lugs for easy panel mounting of the valve. Pressure Rating - 150 psi @ 70°F (non-shock). Molded-in Lugs for Panel Mounting - 1/4” size. NSF Approved, All PVC Construction. 

Hayward Needle Valves are used for accurate metering of fluids. Turning the thumb wheel moves a tapered piston into the Teflon® seat to control the flow down to a few drops per minute. Precision molded, fine-pitched stem threads permit this very fine metering flow control. Pressure Rating - 150 psi @ 70°F (non-shock). 

Produced in two styles: Globe pattern (straight 180°) and Angle pattern (90°). NSF standard 14 & 61 compliant, FDA, USDA and USP standards met or exceeded. Fine metering control, excellent linearity of flow. No elastomer (O-rings) metals or lubricants. Working pressures to 250 psi @ 70°F. 

Marquest Scientific’s complete line of Throttle Master™ Needle Valves provide precise control with fine adjustment of corrosive and high purity fluids. The developed metering chamber provides for the most reliable stabilization and linearity of flow. Produced in two styles: Globe pattern (straight 180°) and Angle pattern (90°).  Needle finish, SPI/SPE No. 1. Bubble tight, low torque shutoff, long term performance. NSF standard 14 & 61 compliant, FDA, USDA and USP standards met or exceeded. Needle stem is PTFE sealed for excellent chemical resistance
