AVENTICS Shuttle Valve 5340.170.100 | Yarder Pneumatic Air Valve

The AVENTICS Shuttle Valve 5340.170.100 (Bosch Rexroth) is a heavy-duty pneumatic double check valve designed for dual-signal control circuits on logging yarders, winch drum brakes, and heavy equipment automation. Operating as a pneumatic “OR” logic gate, it automatically routes the highest pressure signal from two independent supply lines to a single outlet while sealing off the lower-pressure input. Features a durable die-cast aluminum housing for high-vibration forestry operations.

Ensure precise dual-signal pneumatic routing and safety logic on heavy logging equipment with the genuine AVENTICS Shuttle Valve 5340.170.100. Manufactured by AVENTICS (Bosch Rexroth), this high-reliability pneumatic shuttle valve (also known as a double check valve or logic “OR” gate) automatically compares pressure signals from two separate supply lines and routes the higher pressure line to a single outlet port while preventing backflow into the inactive line.

Yarder Dual-Control & Winch Interlocks

On cable logging yarders, winch drum actuators, clutches, and emergency holding brakes often require signal inputs from multiple control points—such as an operator cab foot pedal combined with a secondary hand control or remote override. The AVENTICS 5340.170.100 Shuttle Valve senses which line is pressurized highest and immediately directs air flow to the brake or clutch actuator, completely isolating the unpressurized line to prevent signal leakage on Madill, Skagit, and Thunderbird yarders.

Fast Pneumatic Logic & Circuit Protection

Acting as a zero-leakage directional logic element, the 5340.170.100 valve delivers immediate shuttle response under continuous cycling. It prevents back-feeding air into secondary control valves, protecting delicate pilot controls, throttle actuators, and safety interlocks across heavy forestry equipment.

Heavy-Duty Cast Aluminum Construction

Built for demanding off-highway logging environments, this valve features a rugged, compact die-cast aluminum housing that withstands high mechanical vibration, extreme operating temperature swings, and outdoor moisture exposure.
