Description
The Design 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 Design D4 valve also
makes an excellent dump valve for high-pressure
separators and scrubbers.
