1. Introduction
The following instructions are designed to assist maintenance
personnel in performing most of the maintenance required on the
10000 Series valve.
GE has highly skilled service people around the world available
for startup, maintenance and repair of our valves and component
parts. In addition, a regularly scheduled training program is
conducted to train customer service and instrumentation personnel
in the operation, maintenance and application of our control valves
and instruments. Arrangements for these services can be
made through your local GE Representative. When performing
maintenance use only GE replacement parts. Parts are obtainable
through your local Masoneilan Representative. When ordering
parts always include Model and Serial Number of the unit being
repaired. These installation and maintenance instructions apply
to all sizes and ratings of the Masoneilan 10000 Series control
valves, regardless of the type of trim used. The model number,
size and rating of the valve are shown on the identification
tags located on the actuator. Refer to Figure 1 to identify
valve nomenclature.
2. Unpacking
Care must be exercised when unpacking the valve to prevent
damage to the accessories and component parts. Should any
problems arise, contact your GE Representative or Sales Office.
3. Installation
The valve must be installed with the flow entering between the
seats. In addition, the upper plug must be installed so that the larger
of the two V-notches in the plug is oriented to face the inlet of the
valve.
3.1 Before installing the valve in the line, clean piping and valve of
all foreign materials, such as welding chips, scale, oil, grease or
dirt. Gasket surfaces should be thoroughly cleaned to ensure
leak-proof joints.
3.2 To allow for in-line inspection, maintenance and removal of
the valve without service interruption, provide a manually
operated stop valve on each side of the 10000 Series valve with
a manually operated throttling valve mounted in the bypass
line (See Figure 2).

3.3 The valve must be installed so that the control substance
will flow through the valve body in the direction indicated by
the flow arrow located on the body or the words
in and out
stamped on end connections. In addition, see CAUTION above.
3.4 Where insulation of the valve body is required, do not insulate
the valve bonnet.
4. Air Piping
The actuator is designed to accept 1/4" NPT air supply piping. Use
1/4" OD tubing or equivalent for all air lines. If the air line exceeds 25
feet in length or if the valve is equipped with volume boosters, 3/8"
tubing is preferred. All connections must be free of leaks.
Do not exceed loading pressure indicated on the warning tag
located on the diaphragm cover. If no tag is present please consult
the actuator instruction manual or consult the factory.
