Valve With Stop Mechanism

摘要

In the specification and drawings, a valve is described and shown having a first and second valve seat carrier, a valve seat associated with each valve seat carrier, and a valve ball between the valve seats. The valve further includes a stop mechanism operatively connected to at least a first valve seat, the stop mechanism limiting travel of the first valve seat towards the valve ball such that the valve ball may be push away from a sealing engagement with the first valve seat.
