Profile: The Peter Smith Valve Company Limited specializes in the manufacture of small to medium size valves for the control of fluids and gases in most pipe conveying systems. We also manufacture in cast iron, cast steel, and gunmetal, for use by major industries, water authorities, and marine applications. Our valves include globe stop, angle stop, equilibrium ball float, and swing check valves. Our equilibrium ball float valves gave a bolted cover plate to protect seal and cylinder from the ingress of debris, and have adjustable float for optimum water level control. Parallel slide valves are fitted with a back seating device to further protect the gland packing when fully open.
