Series BV2 Electric and Pneumatic Flanged Ball Valves
NEW – Low Cost Flanged Ball Valve Package
New Series BV2 Electric and Pneumatic Flanged Ball Valves offer ANSI 150# flanged ends for easy installation. 1/2`` through 4`` sizes are standard for great flow rates with minimal pressure drop. The valve features a blowout-proof stem for added safety, reinforced Teflon seats and seals for longer life, and a 316SS ball for better performance. Actuators are direct mounted creating a compact assembly for tight spaces. Double o-ring stem seals assure leak free operation.
The BV2 Series is an economical automated valve package with either an electric or pneumatic actuator. Electric actuated models are weatherproof, NEMA 4, powered by standard 115 VAC supply, and are available in either two-position or proportional control. Two-position actuators use the 115 VAC input to drive the valve open or closed, while the modulating actuator accepts a 4 to 20 mA input for infinite valve positioning.
Series SFI-100T Sight Flow Indicator
Low Cost Sight Flow Indicator/Transmitter - Durable Construction for Demanding Applications
The Series SFI-100T Sight Flow Indicator from the W. E. Anderson Division of Dwyer Instruments, Inc. is a low cost, durable paddlewheel style flow indicator with output sensor. Patented flow sensor uses no magnets in the paddlewheel to attract ferrous materials. Construction is of a rugged, solid brass body with tempered glass window that enables viewing of the bright red PBT paddlewheel.
Units are constructed of all ultraviolet stabilized materials for outdoor service. The A-711T output sensor has a pulsed VDC output for flow rate and totalization. For added versatility there are two output choices of 5 VDC or a VDC equal to the input power supplied of 8 to 28 VDC. The output is compatible with digital rate meters/totalizers and other electronic systems.
The SFI-100T has an excellent pressure rating of 125 psi (8.62 bar), temperature rating of 100°F (93°C), and chemical compatibility. The SFI-100T is compact and weatherproof, and the A-711T output sensor package can be replaced on existing units in the field. Easy maintenance is assured with interior access afforded by the removable front window. Unit is perfect for water purification, laser cooling, water injection, redi-mix concrete trucks, chillers, and other demanding applications.
Series 7112B Spirahelic® Pressure Gage with Diaphragm Seal
Stainless Steel Diaphragm Seal for Spirahelic® Pressure Gage
Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its SERIES 7112B SPIRAHELIC® PRESSURE GAGE WITH DIAPHRAGM SEAL.
Due to the small volume of the triple wound Bourdon tube inside the Spirahelic® gage, a much smaller diaphragm seal may be selected versus a standard ``C`` Bourdon tube gage. This smaller seal is extremely compact, light weight, and more economic than standard diaphragm seals.
Diaphragm seals are available with 316L SS wetted parts and are offered on models with pressure ranges up to 1000 psig. An optional 1/4`` NPT flush port is available for applications such as water treatment plants that require a clean-out line to maintain proper gage performance.
