• Flush mounted actuation means no brackets or couplings are required and there are fewer nuts and bolts.
• A fully adjustable stem packing allows for 180-degree wrench clearance for adjustment.
• It’s capable of sealing against pressure and vacuum without packing modification.
• The interference fit design provides a bidirectional tight shutoff.
• The extended neck provides two inches of pipeline insulation.
• The standard K-LOK flange surfaces are uninterrupted, which allows standard spiral wound gaskets to be used.
• No travel stops are required, making adjustment and maintenance much easier.
• The rocker arm packing allows for uneven tightening of the gland bolts without side loading the system packing.
• The Double offset disc design provides the disc with a camming effect that lifts the disc away from the seat, thereby reducing seat contact wear.
• A fire-safe seat configuration allows for bidirectional service and constant two-point seal of the metal and RTFE seat components. This allows partial burn of the seat without excessive leakage.

While the cast ductile iron or silicon bronze housings, bronze and steel gears, shafts and hardware resist the marine corrosion. 

They are also the ideal choice for applications requiring low magnetic components. Built to MIL-M-17059 or MIL-M-17060 to provide extended life under the worst shipboard conditions. As well as being compact and durable enough to reduce the stress on smaller valves where the Navy High Shock and Vibration qualification is required.

• Non-intrusive control via USB interface
• LED digital display of status & diagnostics, non-intrusive
• Smart actuators—PROFIBUS, LonWorks®, ModBus® and DeviceNet™ right angle gearbox for limited overhead locations

While tailoring to specific services for maximum efficiency, thanks to the stream lined design all throughout the valve. That is encapsulated by the body that is designed to withstand extremely high internal pressures and line strains. All while having the ability to start and stop the flow by sliding the disc across the stream. Therefore, engineered for use in either full open or full closed positions, but not recommended for throttling. As it is the only valve that permits unrestricted flow in the full open position.

SPECIFICATIONS

FEATURES

• The true guiding system in the body prevents contact between the seating surfaces until the valve is almost closed
• Bonnets are designed with a large, deep stuffing box equipped with a gland so that, when wide open, the valve can be repacked while under pressure
• Sizes up to and including 4” feature integral yoke and bonnet construction, while sizes 4-1/2” and above have bolted yoke
