Upgrade your tank trailer's parking brake control system with the WM325 Park Brake Valve by Williams Controls. This robust valve ensures precise and reliable parking brake engagement with its three-way, pull-to-open and push-to-close design, and maintains consistent pressure for dependable performance. Additionally, it features an automatic deactivation mechanism for enhanced safety: when the inlet pressure drops below 35 psi the valve exhausts downstream pressure to apply the spring brakes.
