Piston Valve - Watts Mixing Valve - Replacing A Water Valve
Piston Valve
A piston valve is a device used to control the motion of a fluid along a tube or pipe by means of the linear motion of a piston within a chamber or cylinder.
A type of gas-distribution valve, in which an oscillating piston covers and uncovers circumferential openings in a cylinder.
(Piston valves) Piston valves are an integral part of the cylinder arrangement of a steam locomotive. They control the admission and exhaustion of steam from the cylinders, enabling a locomotive to move under its own power.
Piston from said damage
This is the cylinder - after said damage....
In Detail: The #3 ex gasket was blown - thus letting cold air into the chamber (when engine was turned off) and the lattice of the metal in the valve was ruined, and the #3 ex valve head broke off, slammed the ex seat sideways, bashed up the cylinder, got stuck in between the #3intake valve and the piston and shoved the intake valve into the head, and thus breaking the #3 intake rocker arm literally in 2, bending the pushrod, AND exploding the lifter inside the case... luckily, the case, crank, rods, were all undamaged.
