Installation
All personnel working on valves must be qualified to work on refrigeration
systems. If there are any questions contact Sporlan Division - Refrigeration
Business Unit before proceeding with the work.
All valves are packed for a maximum protection. Unpack carefully. Check the carton
to make sure all items are unpacked, see Figure 1 for the list of items included.
Do not remove the protective coverings from the inlet and outlet of the valve until
the valve is ready to be installed. Protect the inside of the valve from dirt and chips
before and during installation. In the event the valve is left disassembled for any
length of time, protecting the components is essential. Place the components in a
plastic bag and store them in an area where they will not be damaged.
The valve should be installed in a location where it is easily accessible for
adjustment and maintenance. The location should be such that the body cannot be
easily damaged by material handing equipment. Proper indicating gauges should
be installed to be easily visible to the operating engineer for system checks and
adjustment purposes.
The valve should be disassembled before welding to prevent damage to o-rings
and teflon (PTFE) components. First remove the port plate by unbolting the bolts as
shown in Figure 2. If the port plate does not come apart easily, rotate the port plate
45º and use the corners to pry the port plate out. If using a tool, such as a screw
driver, it is important to be careful not to damage any gasket surfaces.
The current port plate gasket must be removed, as shown in Figure 3, and
discarded. A replacement gasket is provided with every purchase of a new valve.
The PEV valves must be mounted in the upright horizontal position with the actuator
on the top.
The valve must be installed with the arrow pointing in the direction of
flow for the valve to function properly.
Installers need to follow a WPS (Welding Procedure Specification) for all welding.
The procedure and welder doing the weld must be qualified to perform that
procedure.
The codes applicable to the welding of socket weld valves require that the pipe
be inserted into the socket until bottomed against the stop, then backed out
approximately
1
⁄
16
of an inch (1.6 mm) before welding. Use of welding rings is
optional but recommended for butt weld valves. They help alignment, control gap
for full penetration welding, and reduce welding debris entry.
