Rock Valve
No other sequencing valve combines lowest cost per yard maintenance costs and ease of rebuilding as the Rock Valve. With over twenty years of development and field-tested toughness, the Rock Valve from Schwing remains the most effective concrete valve available.
The Big Rock
is optional on some models and extends the valve and housing to easily keep up with the requirements of high volume pours even with the harshest mixes. The patented design keeps the Rock Valve in adjustment automatically to maintain pressure on the concrete for long-term, trouble-free operation.
