Inline check valve 19/25 mm

The Whale LV1219 non-return valve is an accessory that belongs to the Supersub / Orca Auto 1300 range. It is designed to be compatible with the electric bilge drainage systems of this range.

This Whale LV1219 inline check valve is designed for use with 19 mm and 25 mm diameter hoses. These dimensions are critical to ensure a proper connection to your bilge system.

The Whale LV1219 inline check valve is specifically designed for electric bilge pumping. Its function is to prevent backflow into the bilge once the pump has stopped, ensuring efficient and sustained drainage.

The primary role of this check valve is to prevent water from flowing back into the bilge drainage circuit. It ensures that pumped water is not returned to the bilge, keeping it dry and protecting the pump from unnecessary operation.

This check valve is manufactured by Whale, a recognized specialist in marine equipment, particularly for marine pumping and plumbing systems.

The exact reference for this inline check valve is LV1219.

Yes, this check valve is specifically designed for electric bilge pumping, which requires adaptation to the marine environment and seawater.

This check valve is designed to be connected to pipes of two different diameters: 19 mm and 25 mm. It provides flexibility for various installations.

Yes, this check valve is specifically designed for use in electric bilge drainage systems, making it compatible with most electric bilge pumps.

Yes, as its name suggests ("inline"), this valve is designed to be installed directly in the discharge line of your bilge system, between the pump and the outlet.

A check valve is a mechanical device that allows a fluid (here, water) to flow in only one direction. It opens under the pressure of the fluid moving in the desired direction and closes automatically to prevent any reverse flow, thereby preventing water from returning into the bilge.

This check valve is installed inline on the discharge hose of your bilge pump. Simply cut the hose at the desired location, insert the valve, and secure it firmly to the hose ends using hose clamps sized for 19 mm or 25 mm diameters.

Although many check valves operate more efficiently in a specific orientation, this inline check valve is generally designed to function effectively in any orientation (horizontal, vertical, or angled), as long as the flow direction is respected.

Yes, a check valve must be installed in the correct direction to function properly. There is usually an arrow or marking on the valve body indicating the permitted water flow direction. Ensure this arrow points toward the boat's outlet.

To secure this check valve to a pipe, you will need hose clamps (also called Jubilee clips) sized for your pipe diameter (19 mm or 25 mm). It is recommended to use stainless steel clamps for increased durability in a marine environment.

The check valve is typically installed on the discharge line, after the bilge pump and before the through-hull fitting. Its ideal placement is as close as possible to the pump to minimize the volume of water that could backflow between the valve and the pump.

Yes, this check valve is fully compatible with pipes having an internal diameter of 19 mm.

Yes, this non-return valve is also compatible with pipes having an internal diameter of 25 mm, providing versatility for different installations.

Yes, this non-return valve is a standard component that can be used with most electric bilge pumps from other brands, provided the pipe diameters (19 mm or 25 mm) are respected.

Yes, since this check valve is a Whale product and is mentioned in the product context as being linked to the "Supersub / Orca Auto 1300", it is compatible with these Whale bilge pump ranges, provided the pipe diameters match.
