John Crane CVU and CVH sets cover a wide range of fluids, including acids, caustics and solvents at high temperatures and pressures. These automatic packings have superior sealing abilities, making them ideal for critical service applications.
They require little or no gland adjustment and generate very low friction, heat and wear, thus extending valve stem life and reducing repair or replacement costs. Made from high-purity PTFE, CVU and CVH sets contain no lubricants or dispersions, making them well suited for non-contaminating services.
