for Fisher N600 Series Ball valves used on LP-Gas and

anhydrous ammonia (NH3) service.

Description

LP-Gas and NH

Maximum Operating Pressure: 1000 psig / 68.9 bar

Ball valves are used at bulk plants to control gas flow
in the piping system, at storage tanks, on trucks and at
pumps or compressors.

For LP-Gas service, a hydrostatic relief valve (Type H124)
or a vent valve be installed when liquid product can be
trapped in a hydrostatic state between to shutoff valves.

Type N610L – Steel or Stainless Steel valves for either
LP-Gas or NH
DN 50 to 80 only, each valve has PTFE packing for sealing

service. Ranging in size from NPS 2 to 3 /

against leakage.

N600L Series configurations are suitable for low­temperature operating conditions.

3 FNPT N610L-24

Temperature Capabilities:
N600L Series: -60 to 450ºF / -51 to 232ºC

Use pipe compound on the threaded joints. Make sure the
compound or ‘pipe dope’ is suitable for the service conditions.

Pull the piping into the valve hand tight, and then wrench
tighten the piping for approximately two additional turns.
Do not install the piping with such extreme torque that the
piping can cut threads into the valve. This can cause valve
distortion and affect the internal working parts. Larger size
valves may require an additional amount of torque to obtain
a leak free connection.

After installation, test the inlet and outlet connections and around
the stem for leaks using an approved leak detector solution.

CAUTION

If the valve is to be used in service other than
LP-Gas or Anhydrous Ammonia, contact the
factory to determine if the valve materials are
suitable for the particular service.
