MILWAUKEE VALVE P2519A - 300 Swing Check Valve, Aluminium, 3 Inch Valve Size

Milwaukee P2519A-300 swing check valve has a disc that swings on a shaft or hinge. It is used for flood prevention in sewage systems, firefighting equipment and toilet flush mechanisms. This aluminium check valve is designed for the one-way flow of gas or liquid. It frequently utilises ball check valves, which combine balls and seats in the same valve body for a leak-free cutoff, in conjunction with diaphragm, piston and metering pumps.

Working Mechanism:

• The disc swings away from the seat to enable forward movement and then swings back onto the seat to prevent reverse flow.
• The valve shuts to stop the flow of the main lubricating oil in reverse while the engine is running.
• The plug uses straight threads to hold the hinge pin within the valve and thus requires a sealing washer.
• These elements along with the sealing result in a low breakaway torque and the possibility of loosening.
• The valve's ability to shut off is influenced by the disc's weight and the return flow.

Features:

• Milwaukee P2519A-300 swing check valve has a horizontal full port design w/ a bolted cover for a strong and leakproof bonnet joint.
• This aluminium check valve ensures durability despite withstanding pressures up to 200 psi in WOG (Water, Oil & Gas).
• It includes stainless steel pins and plugs to prevent contamination.
• This unit comes with a pin rotating disc for improved sealing.
• It is also equipped with seal-welded seat rings to ensure stable shut-off.
• This unit requires a minimum amount of flow for proper functioning.

Standards and Approvals:

• API
• ASTM
• ASME
• MSS

Frequently Asked Questions:

Q. What will happen if the flow through a check valve is insufficient?

A. The disc and related internal components will be in a continual state of motion if the flow through a check valve is insufficient to keep the disc in a fully open and stable position (wobble). Premature wear, loud operation, and vibration are all effects of this installation style.

Q. What flow rate should be maintained?

A. A minimum flow rate of 7.5 feet per second is ideally considered for water systems. Sometimes it is advised to lower the line size when it is difficult to sustain this flow rate.

Q. Can a swing check valve be installed upside down?

A. The flow arrow on a check valve must point in the direction of the flow when it is fitted. The chosen side must be positioned up in installations that are horizontal. Users should never install a check valve upside down.
