37000-FM SHUT-OFF BALL VALVES FOR SAFETY VALVES

Category: ODF & SAE CONNECTIONS

Ways: 2/2

Notes: PERFECT SEAL thanks to the double O.Ring 
ROBUST: brass body, brass cap, stainless steel stem 
TESTED AND 100% TRACEABLE

The 37000-FM series ball valves have been designed to offer a cheaper alternative to our 42000 series change-over valves.
Sturdy and reliable, they are equipped with an AISI 303 stainless steel operating stem to guarantee durability over time. Double O-ring seal in HNBR on the operating stem. Brass closing cap complete with gasket to guarantee the seal even in case of accidental damage to the stem seals. The structural welding process is carried out in OLAB with a dedicated plant. They are 100% tested and on each of them, the date and serial number are printed to certify the positive outcome of the test and to allow traceability over time of the performance data recorded during the test.
The 37000-FM Series ball valves must be assembled between the pressure section of the system and the safety valve. They allow the safety valve to be disassembled to replace it, without having to drain the refrigerant from the system or from a part of the system.
The main construction components of the 37000-FM ball valves are:
  • Body in brass ST-UNI EN12165-CW617N. Brass sleeve TN-UNI EN12164-CW614N Chrome-plated brass ball ST-UNI EN12165-CW617N or TN-UNI EN12164-CW614N. Seats in PTFE Operating stem in AISI 303 stainless steel Stop pin for stem in AISI 304 stainless steel Stem sealing O-ring in HNBR (150 ° C), ST-UNI EN12165-CW617N brass protection cap sealed to the body with OLAB seal Cup sealing O-ring, in neoprene.The main construction components of the 37000-FM ball valves are: Body in brass ST-UNI EN12165-CW617N.

The ball valves of the 37000-FM series can be installed anywhere in the system, upstream of the safety valve. The assembly of the valve can be done independently from the flow direction of the fluid, as the ball valves are bidirectional. All models of this series can be mounted in any position. Before assembling the ball valve make sure that the system is clean. The valves are supplied open to ensure direct connection with the safety valve. The valve must be closed only after the seal has been removed by specialized personnel or an accredited body responsible for checks.
