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
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.
