ChemValve offers lined plug and check valves in a wide variety of sizes and lining materials. Both valve styles offer injection-molding linings, which enables ChemValve to mechanically lock in the liners, whereas other designs use expanded-tube linings, which can create thin spots and stress concentrations. ChemValve’s method produces a consistent, predictable lining thickness very resistant to mechanical and vacuum stresses.
