Advantages Over Butterfly Valves

Advantages Over Butterfly Valves

No disc in waterway to restrict flow or to increase pumping costs

Allows passage of pigging devices

Internal parts can be serviced without cutting valve out of pipeline

25bar rating provides for future pressure increases over the 16bar pressure rating typically found on most butterfly valves

Advantages Over Double-Disc Gate Valves

Zero allowable leakage

Lower torque requirements to operate valve

25 bar pressure rating compared to the 16 bar rating typically found on double-disc gate valves

Epoxy-coated inside and out

Lighter total valve weight

Single-gate construction. Double-disc gate valves have multiple parts that can seize together.

Bypasses, rollers, tracks and scrapers are not needed.

BS664 Gate Valve Main Feature

BS664 Gate Valve Main Feature:
1) The seat ring uses the floating seat ring structure with O-seal ring sealed and pre-tightening force applied to have inlet and outlet dual-way sealed, and the open-close moment with this structure is 1/2 that of the common valves only, able to lightly open and close valve.

2) When fully opened, the valve's channel is smooth and linear,with an extremely small flow resisting coefficient and no pressure loss ,and the pipeline can be cleaned with hair-ball through it .

3) Automatic removal of the high pressure in the internal cavity when the valve is about to close so as to ensure safety.

4) Fully sealed structure leaves a good protective property, suitable for the requirement of 24-hour duty.

A butterfly valve is a valve which can be used for isolating or regulating flow

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.
A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

butterfly valve

There are different kinds of butterfly valves, each adapted for different pressures and different usage. The zero offset butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating. The high performance double offset butterfly valve, used in slightly higher-pressure systems, is offset from the centre line of the disc seat and body seal (offset one), and the centre line of the bore (offset two). This creates a cam action during operation to lift the seat out of the seal resulting in less friction than is created in the zero offset design and decreases its tendency to wear. The valve best suited for high-pressure systems is the triple offset butterfly valve. In this valve the disc seat contact axis is offset, which acts to virtually eliminate sliding contact between disc and seat. In the case of triple offset valves the seat is made of metal so that it can be machined such as to achieve a bubble tight shut-off when in contact with the disc.
