Miteck brochure double flap gate valve

Excellence in Design.

• No rotary action means no need to build clearance (leakage) into the valve.

• Double flaps ensure that the seal is never broken throughout filling and emptying the valve.

• Flapper precision-machined to eliminate air leakage.

• Full-throat opening eliminates bridging, jamming and material build-up.

• In pressurized applications,

our mechanical seal eliminates the potential for shaft-seal

• leakage.Seat and flapper can be reground several times to bring them back to “like new” condition and performance.

PRINCIPLE OF OPERATION

Stage diagram

Flap valve

The Double-Flap gate Airlock Valve is specifically designed to control the rate of material flow

uses two pivoting gates that open and closes in sequence

through a system, while at the same time

to fill and empty the chamber between the gates. Because

preventing air leakage by isolating the processing system’s pressures.

Unlike

a rotary valve that inevitably has some air leakage because of the clearance required between the blades and the housing, The DoubleFlap gate Airlock Valve is designed to seal completely and isn’t subject to the kind of wear that rotary valves would endure under extreme application conditions.

4

As shown in the diagram, the Double-Flap gate Airlock Valve

one of the gates is always closed, the air seal is maintained throughout the fill and dump sequence.

Typical application includes

1 - Batch feeding 2 - Mixing 3 - Drying 4 - Pneumatic Conveying 5 - Material Recovery 6 - Dust Collection

BY OPENING AND CLOSING THE GATES IN SEQUENCE, THE DOUBLE-FLAP GATE AIRLOCK VALVE IS ABLE TO MOVE MATERIAL THROUGH THE VALVE WHILE MAINTAINING A CONSTANT PRESSURE DROP

The Double-Flap gate Airlock Valves are designed for high-pressure applications up to 20 psi and temperature extremes up to 1,650˚F or higher depending upon the application.

Double-flap gate product that can operate reliably in pneumatic conveying systems at these pressures. All models are offered with a choice of pneumatic, electro-mechanical or gravity/ counterweight actuation. A triple flap gate configuration is also available if better suited to your particular application.

The Pneumatic -Series-Double Flapgate Airlock Valves are designed for medium-pressure applications and standard temperatures to 650°F. These units are an excellent, economical alternative to rotary valves. All models match the standard industry flange pattern and height. The low-profile design of the MPSA model enables it to fit in restricted space without costly structural changes.

fit their specific applications,All models match the standard industry flange pattern and height. The low-profile design of the MPSA model enables it to fit in restricted space without costly structural changes.

All models are offered with the following choice of pneumatic,electro-mechanical or gravity/counterweight actuation. We offer a nonwearing seal and will operate flawlessly under all types of continuing process conditions.This would include applications with extreme temperature ranges, abrasive, corrosive materials and high-pressure differentials. During operation, product builds up on the cone until a sufficient load overcomes the counterweight.

The cam alternately opens each cones, allowing material to pass through the separate chambers in batch form and thereby ensuring a gas seal. After cam release, the counterweights (or springs) smoothly return each cone to the sealed position. This type units are suitable for pressure differentials of up to 20 inches water gauge. However with special consideration to the contact points between the inlet and the cone, a seal can be incorporated to allow pressures up to 15 psi.

It operates under principle of gravity ie:flap opens when the material weight above the flap over come the weight of counter weights
