Hayward Flow Control Thermoplastic butterfly valve enables many stopping positions With its advanced, one-piece thermoplastic design and construction, the patent-pending BYV Series Butterfly Valve offers a variety of design advances, including a hand lever that features a 72-spline interlock mechanism that allows for 19 stopping positions (every 5 deg). Pneumatic or electric actuators are available. Available in a variety of thermoplastic materials (for the body, disc and liner), in sizes from 2 to 12 in. (DN50–300), these butterfly valves have a stem-bearing and seal-retainer design that enables accurate stem positioning and retention, says the firm. — Hayward Flow Control, Clemmons, N.C. www.haywardflowcontrol.com   Valve handles high-molecular-weight fluids in compressors Dresser-Rand The Magnum HammerHead valve is a versatile valve that can be applied to all brands of reciprocating compressors, and is specifically designed for applications involving high-molecular-weight fluids at both low and high compressor speeds. This valve’s design has been re-engineered using computational fluid dynamics and finite element analysis, improving the valve flow area by 60% compared to standard Magnum valves.…
