Butterfly Valve
The high-performance DiskFlo Butterfly Valve is used to achieve bi-directional bubble-tight shutoff while maintaining low breakout torque at high and low pressure drops. The high-performance DiskFlo Butterfly Valve uses pressure assisted Jam-lever toggle seating concepts. By utilizing the pressure drop across the valve to aid the seating process, Jam-lever toggle seating assures low breakout torque.
The need for strong actuator seating force is reduced since much of the force is supplied by the fluid pressure. To achieve especially high-performance throttling, even in large pressure drops close to the seat, it is combined with a MASCOT high thrust cylinder actuator and a double eccentric cammed disc.
Flow Characteristics
The inherent flow characteristic of the DiskFlo valve is a modified parabolic. Other characteristic curves are achievable by means of a MASCOT HiFlo Positioner or a SMART positioner.
VFlo – Segmented (V-Notch) Ball Valve
The VFlo – Segmented Ball Valve is designed to provide effective control for demanding applications. It is a rugged design segmented ball valve which overcomes the problems of harsh, particle entrained processes, and fibrous/unclean services. The VFlo also provides accurate, reliable control in a broad range of applications, such as Chemical, Power and Oil & Gas, Petro-Chemical & Pulp & Paper.
The VFlo addresses and solves many long-standing challenges faced by traditional ball valves like:
- Piping forces that unevenly load the seal
- Low rangeability due to limited orifice characterization
- Unsatisfactory shutoff capabilities
EFlo – Eccentric Plug Valve
Salient Features
- Non-Crossover Shaft:
- Pocket-less flow-path tolerates slurries, even up to 3% paper stock.
- Unobstructed flow when fully open.
- Up to 70% greater capacity than other ERP control valves.
- Not eroded by process-born particles.
- Eccentric Rotary Plug:
- Plug does not rub seat ring. Less wear, less friction, more precision.
- Stable throttling, low dynamic torque.
- Stable throttling in either flow direction.
- Inherently Linear characteristic.
- Flow direction assists movement to safety position on air-failure.
- Robust, rigid seat and plug give increased durability.
- Tight Shut-off, Class IV (Metal Seat), Class VI (Soft Seat), even after prolonged usage.
- Separate Bonnet and Integral Shaft Collar:
- A positive anti-blowout as a standard feature, in full compliance with ASME B16.34 Section 6.5.1, ensures that the shaft cannot blow out, even if the actuator is removed.
- Trim Choices & Plug Design:
- Hardened plug gives high performance and long service life.
- Flow Capacity can be closely matched to the process application.
- Full Area, 75 / 70%, 40% seats are economical to replace when optimizing flow capacity or changing service conditions.
FlushFlo – Flush Bottom Valve
The MASCOT FlushFlo is used at the bottom of large tanks / digesters and driers to discharge the processed fluid to a further process.
The inlet and outlet flange is completely customizable to the customer’s tank and it is available in a varying angles of 90°, 120° & 135°.
The Plug can be Quick Opening type or with a Linear, Equal Percentage Characteristic. The Self Aligning seat ring ensures tight shutoff without Lapping even after prolonged use. The plug can be equipped with an RTD for temperature measurement and control.
