They are commonly used where a minimum of pressure drop is important because they offer typically no resistance to flow when fully open. Throtting is not conductive to accurate and consistent flow control. Also the valves may be damaged by the high velocity across the seats. They function best fully open or fully closed.  Check Valve FLOWSERVE  Atomac Lined Ball Check Valve Type ARV2  Atomac Lined 45° Ball Check Valve Type ARL  Atomac Lined Swing Check Valve Type ARK2 PEGLER • BS5154 PN32 Series B • Horizontal fixing • Metal seat and prong type metal disc • Body arrow indicates direction of flow  Bronze Horizontal Check Valve Type 1039  Bronze Swing Check Valve Type 1060A WALWORTH  walworth cast steel check valves #150.pdf  walworth cast steel check valves #300.pdf  walworth cast steel check valves #600.pdf For more information, please contact 139 Soi Nuanchan 34, Nuanchan Road, Nuanchan, Buengkum, Bangkok 10230 Tel : 0-2792-9333 Fax : 0-2946-1755~6 Email : sales@alphagroup.co.th       Please Select Alpha Alpha Heat Pump Alphair Aquametro Ari Armaturen Armstrong Asco BOA Clorius DK EFI EI Williams Everlasting Flowserve Flowserve - Schmidt Armaturen Giacomini HKC Ivaltec Jako JK Keckley Kempchen Klinger Klinger Schoneberg Omal Pegler Raphael Schmidt Armaturen Socla Socla - Desbordes Spence Super Klean Superlok Titan Valas Visilume Walworth Watts YTC Zipson ZOOK Please Select Actuator Air Vent Ball Valve Blowdown Valve Bolting Application Service Butterfly Valve Check Valve Codensate Recovery Equipment Control Valve Expansion Joint Flow Sight Glass/Check Foot Valve Gasket Gate Valve Gauge Globe Valve Heat Pump Hydraulic Valve Knife Gate Valve Level Gauge Liquid Drainer Needle Valve Oil Meter Piston Valve Positioner Pressure Reducing Valve Pressure Regulating Valve Ring Cutting Machine Rupture Disk Safety Valve Steam Separator Stethoscope Steam Trap Steam System Web Monitoring Strainer Temperature Regulator Timer Tube and Pipe Fittings Vacuum Breaker Vent Silencers Water Heating & Mixing     Home Products Services About us Contact Us Supplier Links Copyright 2009 Alpha Group Co., Ltd.
