Product Overview
The Dwyer SAE-50 butterfly valve is designed as a compact hydraulic reservoir shut-off valve for fluid power systems and hydraulic pump installations. Its construction addresses the demanding requirements of hydraulic applications while providing a practical solution for reservoir isolation and flow adjustment.
A key feature is the O-ring flange face seal, which satisfies the dimensional specifications of SAE J518. This sealing arrangement is designed to provide bubble-tight reservoir shutoff up to 25 psi (1.72 bar) while the valve body shell is rated to 500 psi (34.5 bar).
The SAE-50 uses a 5" S.A.E. flange size in a 2-way lug butterfly configuration. Its compact envelope helps reduce the installation space required around hydraulic reservoirs and pump systems.
Temperature capability depends on the seal material. With standard Buna-N seals, the valve supports temperatures up to 180°F (82.2°C). Optional fluoroelastomer seals increase the maximum operating temperature to 300°F (149°C).
The valve also features an open/close detent position lock that can be infinitely positioned to achieve the desired flow rate. Its special construction helps dampen vibrations associated with hydraulic pumps and pumping systems.
Optional locking handles and fluoroelastomer seals are available for applications requiring additional configuration flexibility.
For installations requiring a smaller SAE flange size, the Dwyer SAE-40 uses the same SAE J518 design and sealing principle in a 4" size.

Frequently Asked Questions
What flange standard does the SAE-50 meet?
The SAE-50 uses an O-ring flange face seal that satisfies the dimensional specifications of SAE J518.
What is the bubble-tight shutoff rating?
The valve provides bubble-tight reservoir shutoff up to 25 psi (1.72 bar). The body shell is rated to 500 psi (34.5 bar).
What temperature range does the SAE-50 support?
With standard Buna-N seals, the maximum operating temperature is 180°F (82.2°C). With optional fluoroelastomer seals, the maximum operating temperature is 300°F (149°C).
What size is the SAE-50?
The SAE-50 uses a 5" S.A.E. flange size.
Can the flow position be adjusted?
Yes. The valve features an open/close detent position lock that can be infinitely positioned to achieve the desired flow rate.
Does the SAE-50 help reduce hydraulic system vibration?
Its special construction is designed to dampen vibrations associated with hydraulic pumps and pumping systems.
What is the difference between the SAE-50 and SAE-40?
The primary difference is the flange size. The SAE-50 is the 5" version, while the SAE-40 uses the same SAE J518 design and sealing principle in a 4" size.
