Abstract
A modular lining system for a valve body for use in fluid handling systems including fluid transport tankers, and a method for lining a valve body using the modular lining system. The lining system is slidably inserted into the valve body to protect the valve body from corrosive or other damaging materials. The liners are placed such that they are easily removable for cleaning or replacing when damaged. An actuator comprising a piston is actuated within one of the liners to selectively allow and stop fluid flow.
