Introduction

Scope of Manual

This instruction manual includes installation, maintenance, and parts information for NPS 1 through NPS 4 Fisher RSS

lined globe valves. Refer to separate manuals for instructions covering the actuator, positioner, and accessories.

Description

The RSS lined globe-style valve (figure 1) has pure-modified PTFE trim parts, push-down-to- close action, and positive

shutoff. This valve is intended for applications involving severely corrosive and toxic flowing media, and is well-suited

for pure media applications, as well. The RSS valve body provides an economical alternative to alloy valve bodies in a

wide variety of applications.

Do not install, operate, or maintain an RSS valve without being fully trained and qualified in valve, actuator, and

accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to

carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you

have any questions about these instructions, contact your Emerson Process Management sales office before

proceeding.

Instruction Manual D101299X012 RSS Valve September 2014 Specifications Specifications for the RSS valve are shown in table 1. If the valve is shipped with the actuator, some of the valve specifications are on the valve nameplate, which is attached to the actuator. If the valve is shipped without the actuator, the valve nameplate is wired to the valve. Installation WARNING Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury.

Instruction Manual RSS Valve D101299X012 September 2014 1. The control valve assembly should be installed in a horizontal pipeline with the valve stem in a vertical position. Before installing in any other orientation, consult your Emerson Process Management sales office. Flow through the valve must be in the direction indicated by the arrow cast on the valve (figure 7). 2.

Instruction Manual D101299X012 RSS Valve September 2014 Maintenance Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance frequency depends on the severity of service conditions. This section includes instructions for packing and trim replacement. All these maintenance operations may be performed with the valve in the line. WARNING Avoid personal injury or property damage from sudden release of process pressure or bursting of parts.

The packing box is only a safety measure in case of a leak through the bellows (key 6). Therefore, the packing follower (key 11) is tightened to 1.13 NSm (10 lbfSin) of torque and then loosened one half turn. To detect a leak through the bellows (key 6), the bonnet (key 2) can be provided with a connection for leak-off piping.

At all bolting locations, the gap must be equal and approximately 2.0 mm (0.080 inches) for NPS 1 through 4 valves. In order to keep the gap equal, the individual bolts may have to be tightened to different torque levels. Note Due to the cold flowing tendency of the valve liner, this procedure should be repeated upon installation and after the first thermal cycle of the valve. 11.
