Fisher™ D4 Control Valve

The Fisher D4 control valve is a compact, rugged globe valve designed primarily for high-pressure, throttling applications using either pneumatic or electric control. This valve is ideal for use on pressure and flow control applications within the oil and gas production industry. These valves are especially useful for either throttling or on/off control of liquids or gases which are gritty, sticky, or which have a tendency to build-up on internal valve parts.
