Its two-delivery-port layout and included mounting bracket allow it to settle into a wide range of chassis configurations without modification. The valve’s 4.0 PSI cracking pressure helps promote consistent brake response in setups that rely on steady modulation during both loaded and lightly loaded conditions. Construction choices prioritize resistance to contamination that is often introduced through older system plumbing. The Sealco 110412 is designed for applications that require optimized air transfer through the rear brake circuits.
