Brief introduction:The Fisher/Fisher D4 Control Valve is a compact, rugged straight-through valve designed primarily for high-pressure throttling applications and is available with pneumatic or electric control. This valve is best suited for pressure and flow control applications in the oil and gas production industry. These valves are particularly suitable for throttling or on/off control of fluids that contain sand, viscous oil and gas, or have a tendency to clog valve trims. The bonnet is equipped with a one-piece flange that can be tightened with a hammer nut for bonnet-to-body connections. Snap rings are not used because they can fail in acidic environments or atmospheric corrosion applications.
Features:
The removable grooved pin allows for quick and easy replacement of the plug.
The compact design allows it to be installed where space is at a premium. The screw-fastened body features a compact flange spacing size and the flanged body meets ISA-75 standards for maximum versatility.
The hammer nut bonnet/body connection requires minimal tools for repair or maintenance, eliminating the need to disassemble the valve body from the piping system. The seat ring can be removed using a standard socket sleeve.
Micro-Form trims are standard for throttling or switching applications at no additional cost.
A choice of ports up to 31.8 mm (1.25 in) in diameter, a variety of end connections and trim materials make these valves suitable for a wide range of applications, including acidic environments.
