Category: TRADITIONAL REFRIGERATION SYSTEMS
CHECK VALVE SERIES
YELLOW BRASS BODY AND COPPER PIPES
SEAL IN PTFE AND NEOPRENE RUBBERIZED SHEET
DESIGNED FOR PROFESSIONAL REFRIGERATION SYSTEMS
PS : 45 BAR
TS : -35°C +105°C
Serie 33100 : TS : -35°C +160°C
HIGHLY ROBUST
SAFE: guaranteed seal
30 MM COIL
Class H
Double OR sealing
Opening differential pressure from 0.1-0.3-1.5 bar
100% TESTED, with modern 100% helium plant, each valve bears
the date and serial number proving that it has passed the test and
allowing traceability of the performance data measured during testing
over time
The check valves are designed to be installed on refrigeration and air-conditioning systems for domestic and industrial use. It’s possible to use them with all the refrigerant fluids of group II (as defined in Article 13, chapter 1, Point b of Directive 2014/68/EU, with reference to EC Regulation No.1272/2008) and they are defined as “pressure equipments”, as described in Directive 2014/68/UE, Art.2 point 5 and Art.4 point 1.C
Brass body TN-UNI EN12164-CW614N (33000 series) or ST-UNI EN12165-CW617N (33100 series) Closing fitting made of brass TN-UNI EN12164-CW614N (33000 series) Cover made of brass ST-NI EN12165-CW617N (33100 series) Sealing O-ring made of Neoprene (HNBR option) Stainless steel spring Guide bush for brass gasket TN-UNI EN12164-CW614N Sealing gasket made of PTFE Brass pipe UNI-EN 12735/1 with ODF pocket The main construction components of the check valves of the 33000-FM series are: Hot forged brass EN12164-CW614N for body and cover valves Austenitic stainless steel AISI 3012 for the spring HNBR + PTFE sealing gaskets
At the start-up of circuit is good to be sure that there are not dust or contamination inside the pipes. The arrow direction on body valve should be in accord with the flow direction inside the circuit. All mounting positions are accepted, even if is better to be in accord with the vertical axis. For 33100 series is accepted only the installation with orizontal axis. The braze welding of copper tubes should made by special alloy, with low melting point. The flame should not be directed toward the seals or body of valve, because it can damage the valve in consequence of overheating
