Operating Instructions
Habonim Valves provide tight shut off when used under normal conditions and in accordance with Habonim
’
s
published pressure/temperature chart.
If these valves are used in a partially open (throttled) position, seat life may be reduced. Consult with Habonim for
the proper seat material selection.
On manual operated valves, the valve operation is done by turning the valve handle 90° clockwise to open
(handle is parallel to flow line), and 90° counter clockwise to close (handle is perpendicular to flow line).
For unidirectional designed valves; a flow arrow indicates the flow direction of the valve for proper installation. A
silicone-based lubricant is applied to assist valve break in. The lubricant, if unacceptable, may be removed by a
solvent wash.
If a shut-off valve is installed for end of line service, it must be ensured that it is closed with a blind end
connection and the valve is secured against being opened unintentionally.
WARNING: Never look into the valve bore while the valve is in a flow line. Pressure and
fluids could escape from the valve causing harm or injury.
To prevent leakage, malfunctions resulting from internal wear or seal degradation, the
user must establish a preventive maintenance and inspection program. This program
must include:
1.
Inspection of parts to detect loss of wall thickness which may result in decreased
pressure capacity (see Para. 3 for acceptable reduction of wall thickness).
2.
Routine replacement of seals and inspection for proper operation (See Para. 7 for
maintenance instructions).
Valve operating torques, as published in the Habonim literature, are the normal
expected maximum break-out torques. These torques have been confirmed by
laboratory testing of each valve under controlled conditions. Highly viscous or
abrasive media, frequency of operation and temperature fluctuations could cause an
increase in valve torque.
