Valves, Cut-Out Cocks & Fittings

Dirt Collector & Cut-Out Cock
Easily removed for cleaning, the valve features a centrifugal dirt collector to protect the integrity of the air circulating throughout the brake system. The cut-out function closes communication between the system's control valve and the brake pipe.

Ball-Type Angle Cock
NYAB’s flanged and standard ball-type angle cock with locking handle is for use on all types of conventional freight and intermodal cars, as well as on locomotives. Its rugged construction offers low-torque operation and self-cleaning, leak-free service. Disassembly is easy.

Vent Valve
Our service-proven KM-2 vent valve utilizes a poppet valve design to provide superior and reliable venting, even in the presence of heavy brake pipe contamination. No screen is required at the brake pipe inlet. KM-2 vent valves are used in locomotive applications, and in long car applications in conjunction with DB-60L.

Three-Position Retaining Valve
NYAB’s retaining valve is constructed of high strength, noncorrosive structural plastic, and is a direct replacement for the existing design, offering high reliability and long life. It is 40% lighter and uses 30% fewer parts! The three-position retaining valve controls the brake cylinder exhaust rate or retains a 20 psi brake cylinder pressure, as governed by the position of the manually operated valve handle. The three positions are: Direct Exhaust (EX), Slow Direct (SD), and High Pressure Retain (HP).

Premtec Hoses & HI-FLO® Coupling
Premtec hoses, available in 22" and 33" lengths with HI-FLO standard or locking couplings, are tough, remain flexible at low temperatures, and meet or exceed all AAR specifications. These assemblies offer 55% higher pull-apart resistance, 32% improved air flow with reduced air restriction, improved gasket alignment and rust protection inside and out. An extension coupling adapter is also available, as are special assemblies upon request.
