NEW Circle Seal # 259B-10PP 1-1/4” NPT Check Valve; 3,000 PSIG; # 137-H2

Description

Up for sale is a NEW Circle Seal # 259B-10PP 1-1/4” NPT Check Valve; 3,000 PSIG
The Circle Seal Controls model 259B-10PP Check Valve is constructed in Brass with Buna seals, has 1-1/4″ FNPT connections, and is rated for 0-3000 PSIG service.
Features & Benefits:
• Zero leakage
: Circle Seal check valves are absolutely bubble-tight in leakage tests
• Quick opening / positive closing
: Even at extremely low pressure differential; opening pressures are as low as 0.1 PSIG; the poppet closes at zero flow before return flow starts.
• Maintenance free dependability
: The resilient o-ring absorbs the shock and automatically compensates for normal wear; there are no special seats which require replacing or resurfacing
• Excellent flow characteristics:
The streamlined poppet and full ports offer minimum restriction to flow; the spring retainer has ample ports to allow full flow even when surge pressure forces the poppet against the stop
• No “chatter” or “hammer”:
The pulsating action of shock waves and hammer is absorbed by minor expansion and contraction of the o-ring; the use of the resilient o-ring seal, together with the careful poppet design, insures cushioned, quiet closing
• Satisfactory performance under adverse conditions
: Foreign particles in the fluid stream do not prevent proper sealing; temperature variations do not affect proper functioning of the valve; can be supplied to withstand temperatures from -320 to +400F.
• Adaptable to most fluids
: Metallic and non-metallic parts can be supplied to withstand the action of most commonly used exotic fluids; no special wear resisting materials are required, eliminating the problems of differential expansion and electolytic action from dissimilar metals
• Compact and easily installed
: Efficient straight-line design reduces weight and size; permits mounting in any position; all valves are marked with an arrow to indicate the direction of flow
