Piston, ball, swing, and spring controlled check valve designs for horizontal or vertical (upward flow applications for the most often specified pressure classes are available. A spring can be added to piston check valves not currently equipped with that option if specified on the order.
Vogt's ''Y'' pattern check valves complement our ''Y'' pattern and In-Line repairable globe valve lines used in refineries, chemicals, power and related industries.
Piston and ball check valves should not be used in applications where rusting or rust particles are present or anticipated. Swing check valves are more tolerant for applications of this nature.
Vogt check valves (non spring loaded) should be sized to provide a minimum of 2 psi pressure drop for ball and piston type valves and 1/2 psi for swing check valves. This will assure that the valves will not be subject to noisy operation and premature wear of parts.
Spring loaded piston check valves are the Vogt preference for reciprocating compressor service in which a history of noisy check valve operation has been experienced.
Check valves are designed to prevent reverse flow. Leakage rate for Vogt check valves with metal-to-metal seats are dependent on the amount of back pressure and the viscosity of the flowing medium. Check valves should not be used in gas or low back pressure liquid applications if zero leakage is desired.
