Fisher™ D & DA Control Valves
Enquire about this Product
Fisher D and DA single-port, high-pressure valves are widely used in oil and gas production industries. These valves are especially useful for either throttling or on/off control of liquids or gases which are gritty, sticky, or have a tendency to build-up on internal valve parts. The DA valve is also useful in angle piping or other applications where a self-draining valve is desired.
