RD Weld/Compression End Check Valve (Inlet & Outlet Connecting Steel Tubes)

RD High-Pressure Check Valve

Features
•Type of connection: compression or weld type for steel tubes
•Seal material: FPM (-25℃～+180℃), NBR (-35℃～+100℃), EPDM (-45℃～+130℃)
•Pressure: See "Table of Technical Data"; see the product page for pressure ratings of bright ferrules (-B)
•Cracking pressure (tolerance: ±30%): 0.2bar (standard); 0.5bar (for oils and other high-viscosity liquids); 3bar (optional); <0.06bar (for -Q type)
•RD-*-Q check valve: low cracking pressure; applicable to: 1) micro-pressure; 2) vacuum; 3) applications with low gas flow.
