Introduction

Scope of Manual

This instruction manual provides installation, maintenance, and parts information for the Fisher D4 control valve.

Do not install, operate, or maintain a D4 control 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.

Description

The D4 control valve is a compact, rugged valve designed primarily for high-pressure throttling applications. This valve

is ideal for use on pressure and flow control applications within the oil and gas production industry. The D4 valve also

makes an excellent dump valve for high-pressure separators and scrubbers.

The D4 control valve meets the metallurgical requirements of NACE MR0175/ISO 15156 without environmental limits

for temperatures below 135

_

C (275

_

F). If the temperature is above 135

_

C (275

_

F), the N07718 Belleville washers will

impose some limits, as shown in table 3.
