Constructed with carbon reinforced PTFE piston ring and glass fiber reinforced PTFE main orifice seal, servo-operated EV245B offers stroke length that accelerates heating of medium. Polymer coil types that clip onto valve include BB dc coil for temperatures to 140°C, BB ac and BN dc coil for up to 160°C, and BQ ac coil for up to 185°C. While alignment of double-guided piston and extra closing spring help prevent leakage, erosion-resistant stainless steel valve plate protects seal surface.

Model SR-800 (Sanitary RAM-800) employs piston design that uses O-rings behind Teflon® wall and has no interior spaces where liquids and foreign matter could accumulate. Valve body is constructed of BPE and 3A compliant, 316 stainless steel, and can be autoclaved. Rated for 150 psig product meets ASME BPE-2002 standard requirements and operates in temperatures from 32-300°F. Also suitable for use in food and beverage and API manufacturing industries.
Valve allows sampling under adverse conditions.
RHE America, LLC
Lisle, IL 60532
Apr 19, 2004 Model EPV 25 features pneumatically-operated piston with sample chamber of defined volume. Before sampling operation, chamber is located inside reactor vessel and is continually immersed in product, guaranteeing representative sample. Double sealing of circular slit metallic packing and valve seat allows for sampling during both pressurized and vacuum operation of reactor.
Piston Valve has linear position indicator.
ASCO (Automatic Switch Co., Valve Div.)
Florham Park, NJ 07932
Mar 02, 2004 Angle Body Piston Valve 8290 incorporates miniature 32 mm operator, proportional valve, and HS linear position indicator. Operator angle body valve covers 3/8, ½, and ¾ in. pipe sizes, and HS2/3/4 Linear Position Indicators, supplied with 2 mechanical or Viper switches, mount on top of valve operator in place of visual indicator. HS2/3 indicators are suitable for hazardous locations, while HS4 is suitable for non-hazardous locations.
Valves are piston actuated.
Spirax Sarco Inc.
Blythewood, SC 29016
May 28, 2003 Piston Actuated Valves provide on/off control of media with max operating pressure range of 0â€“290 psi and vacuum to 29 in. Hg. Available 2-way valves come in NC, NO, and bi-directional operation and require separate source of pressure to operate. Bi-directional valves are suited for high-pressure water applications to eliminate water hammer. Standard configurations include 6 line connection sizes from ½â€“2 in. NPT and BSP. Actuators are available in 45, 63, and 90 mm dia.
Piston Intake Valve suits harsh fire service environments.
Akron Brass Co.
Wooster, OH 44691
Jun 06, 2002 Black Maxâ„¢ is made of high strength stainless steel drive components, poly-impregnated aluminum body casting, and polymer piston. Enlarged waterways allow users to maximize water flow (2000 gpm) with minimal friction loss (7 psi at 2000 gpm).
Piston Valve assures lubrication on every part.
East Providence, RI 02914-1342
May 02, 2002 Model 725DA-SS stainless steel, pneumatically operated piston valve applies accurate, uniform dots and stripes of grease without mess, drooling, or maintenance. It employs no seals to wear out, leak, or degrade performance. It offers clean cutoff and external stroke control. Model 725DA-SS can be used in new assembly machines, or can retrofit to existing production lines.
