Sample Specifications - Valve

N/A All 1/4" - 2" thermoplastic ball valves shall be manufactured with PVC Type 1, Grade 1 (ASTM D1784, Cell Classification 12454) or CPVC (ASTM D1784, Cell Classification 23447). All sizes of shall be of true union design. Valve body shall contain an integral top mounting flange with dimensions and bolt circles conforming to ISO 5211. Valve to include as standard sliding lock-out plate that interlocks with integral flange on body for lock-out / tag-out. The valve has four locations for attaching a padlock. Body shall incorporate molded in foot pad for panel or rail mounting. All O-rings shall be EPDM or FPM. Seats shall be PTFE as standard. Seats for 1/4" - 2" valves shall be reversible to allow field rebuild. Valves 2" and smaller shall have a floating ball and System2™ seat carrier design that moves with the seat to affect a double seal to flow through a closed valve, and require no adjustment. The handle shall be retained without any metal fasteners and made from GFPP with UV Inhibitor. Balls must be full-port design and fully sphere shape. Stem shall contain double o-rings, and shall be blowout-proof design. Valve stem design shall be such that any torsional failure occurs outside of the two stem o-rings.

All 1/4" - 2" ball valves shall be pressure-rated for 250 PSI at 70°F non-shock. All sizes of ANSI 150 lb flanged ball valves shall be pressure-rated for 150 PSI at 70°F non-shock. Valves to be NSF/ANSI 61 Listed.

All ball valves shall carry a three-year warranty, and shall be manufactured by Hayward® Flow Control and in the USA.

Sample Specifications - Actuator

N/A All PMD/PMD4 pneumatic actuators shall be constructed from Polyamide (PMD Series) or glass filled Polypropylene (PMD4 Series). The actuators shall be quarter-turn, double-acting (air-to-air), rack-and-pinion (2-piston) design. The internal o-rings shall be Nitrile, and the output shaft shall be Steel. The actuators shall have manual override capability and a position indicator. The actuators shall be NAMUR-style to accommodate direct mounting of a solenoid (side-mount) and/or position feedback limit switches (top-mount). The bottom of the actuators shall contain an ISO5211 mounting pattern to facilitate universal valve mounting. All external mounting hardware shall be stainless steel. A minimum of 80 PSI shall be provided to these actuators for proper torque performance in the field. A maximum of 120 PSI shall be allowed. For proper actuator sizing (per valve type and size), consult with Hayward Flow Control.

All PMD and PMD4 Series actuators shall carry a Global three (3) year warranty, and shall be manufactured by Hayward Flow Control.
