Valves, Cut-Out Cocks & Fittings: Features & Benefits

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-60^®L.

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.

Fittings

NYAB offers a complete line of AAR-approved straight and elbow socket-weld fittings.

Ball Valves

New York Air Brake's non-vented locomotive ball valve seals off air flow to the air circuit connected to its ports. The vented ball valve seals off air pressure on one side and vents air pressure to atmosphere on the other so that components on the vented side of the ball valve can be serviced. Ball valves are available in 1/4 turn shut-off and locking handle shut-off models. Dual Teflon seats combined with our chrome plated balls provide greater durability and extended life.
