N/A The KEN-FLEX™ resilient-hinged check valve provides reduced maintenance and faster closing than most traditional swing check valves. The rubber-encapsulated flapper assembly is the only moving part and is easily accessed through a full-size cover with the valve in line. The resilient flapper material makes KEN-FLEX™ ideal for ”dirty water” applications, and the fast-closing action is ideal for surge prevention. The optional position indicator is spring loaded and provides the added benefit of accelerated closing speed.
