SOV safety lock nut cylinders are designed for mechanical load holding, suitable for applications up to 1,000 tons. These cylinders feature a baked enamel exterior finish and plated pistons that offer excellent corrosion resistance. An overflow port acts as a stroke limiter, ensuring safe operation. Interchangeable hardened grooved saddles come standard, along with a CR-400 coupler and dust cap on all models. They operate on a single-acting load return system.
