Pinch Valve utilizes manual or pneumatic actuator.

November 3, 2014

Designed for shut-off applications, automatic PVG Valve has full bore structure, bubble-tight shut-off, and can be connected to pneumatic system of plant. Inside sleeve is naturally resistant to any scaling which breaks away when valve is closed. It also includes opening tags to ensure valve opens even after long periods of time. Operating with no jamming or clogging, PVG Valve is developed for processes involving abrasion, corrosion, and aggressive slurries. Read More

Throttle Trip Valves are ANSI rated.

December 17, 2013

Combining flow control and emergency shut-off operation in single assembly, Throttle Trip Valves can be manufactured with soft packing, hardened leak-off bushings, and various materials for critical applications. As throttle valves, units regulate flow of steam and gas in large, high-pressure pipe lines. When used as trip valves, they add measure of safety critical to these applications. Valves rapidly shut down flow when tripped manually or automatically to protect valuable equipment. Read More

Ball Valves target instrumentation and control systems.

October 22, 2013

Available with end connections from 1/16–3/8 in. as well as corresponding metric sizes, FloLok® 41, 42, and 43 Series feature forged one-piece body and blowout proof stems. Quarter-turn shutoff valves contain modified PTFE packing for chemical compatibility and extended life over temperature range of -65 to 300°F. Since valves do not rely on system pressure to seal, they seal equally well at both high and low pressures. Remote sensors can be mounted in handles to determine open/close position. Read More

PTFE Needle Valves are corrosionproof.

July 27, 2009

Made of PTFE and PCTFE materials, VT6 6 mm orifice PTFE needle valves are designed for laboratory and industrial applications requiring corrosive gas and liquid regulation or high-purity service. Panel mountable units have 3/8 in. FNPT ports, and can be used in pressure, non-critical vacuum service, or as shut-off valves. PCTFE valve spindles virtually eliminate creeping, while radially compressed PTFE o-ring feature allows quick compression adjustments without disassembly. Read More
