SDA0063A 2 1/2" M12 SAE BUTTERFLY SUCTION VALVE (ALUMINUM)

The SDA0063A 2 1/2" M12 SAE Butterfly Suction Valve is a lightweight aluminum hydraulic valve developed for suction-side applications in hydraulic systems. Featuring a 2 1/2" SAE connection and DIN 63 interface, it is designed to provide efficient shut-off and convenient access to hydraulic pump suction circuits.

Its aluminum construction offers a significant weight advantage compared with conventional cast versions. This makes the SDA0063A particularly suitable for mobile hydraulic equipment, compact power units and machinery where component weight is an important consideration.

The compact butterfly configuration allows the valve to be integrated into hydraulic suction assemblies without occupying excessive installation space.

Lightweight Aluminum Construction

The major advantage of the SDA0063A aluminum butterfly valve is its lightweight construction. Aluminum helps reduce the weight of the suction assembly while providing a durable solution for hydraulic applications.

This characteristic can be especially beneficial in mobile machinery, construction equipment and compact hydraulic power units, where reducing component weight can make installation and maintenance easier.

Compared with a cast-body suction valve of the same nominal size, an aluminum configuration can provide a more weight-efficient solution for hydraulic system designers.

Hydraulic Pump Suction Applications

The SDA0063A is designed for installation on the suction side of hydraulic pumps. It can be positioned between the hydraulic reservoir and pump to provide a manual isolation point within the suction circuit.

Typical applications include:

• Hydraulic power units
• Hydraulic oil reservoirs
• Hydraulic pump suction lines
• Mobile hydraulic machinery
• Construction equipment
• Agricultural machinery
• Industrial machinery
• Hydraulic tank assemblies
• Hydraulic filtration systems
• Oil circulation systems
• Hydraulic maintenance systems

Compact Hydraulic Installation

The 2 1/2" SAE and DIN 63 connection configuration makes the SDA0063A suitable for larger hydraulic suction lines where adequate flow capacity is required.

Its butterfly design provides a compact alternative to larger conventional shut-off valve arrangements. This can help simplify hydraulic piping layouts and make better use of limited installation space around pumps and reservoirs.

The valve can also be integrated with suitable SAE/DIN adaptor flanges and flexible compensators when designing a complete pump suction connection.

Manual Operation

The SDA0063A uses a manually operated mechanism for opening and closing the valve. This provides straightforward control of the hydraulic suction circuit during normal operation, maintenance and servicing.

The valve can therefore be used as an accessible isolation component in hydraulic pump and tank assemblies.

Suitable for Mobile Hydraulic Equipment

The low-weight aluminum construction makes the SDA0063A a practical option for applications where the hydraulic system needs to remain compact and weight-efficient.

Potential applications include:

• Excavators
• Loaders
• Agricultural machinery
• Forestry equipment
• Mobile hydraulic power units
• Construction machinery
• Industrial mobile equipment
• Special-purpose hydraulic machines

Technical Specifications

SDA0063A Advantages

The SDA0063A 2 1/2" SAE aluminum butterfly suction valve combines a large hydraulic connection size with a lightweight and compact construction.

It is an ideal option when a hydraulic system requires a manual suction-line shut-off valve while keeping the overall assembly as light and space-efficient as possible.

With its 2 1/2" SAE connection, DIN 63 interface and M12 mounting, the SDA0063A can be incorporated into hydraulic pump, reservoir and suction-line assemblies across industrial and mobile applications.
