Check-Valves-page

The swing check valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position.

Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.

Ladish Valves swing check product line are manufactured as full port, threaded, socket-weld, flanged or weld end body types. Pressure classes include 150 through 1500.  From our Houston manufacturing facility we offer valves in the following materials: CF8M, CF3M, CF8, CF3, CK20, CG8M, CF8C, CN7M, CW12MW, CY40, CW6MC, N12MV, N7M, M35-1, CZ100, CD3MN and many others.

Gate-Valves-page

The gate valve is the most commonly used valve in industry.  Gate valves are well suited for water, oil and gas service as well as a variety of other fluids.  They are intended for on‐off flow control and should only be used in the fully open or fully closed position.  When fully opened, fluid through the valve is in a straight line, resulting in minimum pressure drop across the valve.  Gate valves are bi‐directional and can be used for flow in either direction.

Ladish Valves gate product line are manufactured as full port, with threaded, socket‐weld, flanged and butt weld ends.  Pressure classes include 150 through 1500.  From our Houston, Texas manufacturing facility, we offer valves in the following materials: CF8M, CF3M, CF8, CF3, CK20, CG8M, CF8C, CN7M, CW12MW, CY40, CW6MC, N12MV, N7M, M35‐1, CZ100, CD3MN and many others.

Globe-Valves-page

The globe valve is used for throttling flow control.  Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve.  The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high pressure drop.  The globe valve is an excellent valve to use for on-off service, but is highly suited for frequent cycling and control of fluids anywhere in amount or volume between the open and closed positions.

The globe valve must be installed in the proper relation to the media flow as indicated by the flow direction arrow marked on the valve body.  This valve is considered uni-directional and must be installed with the pressure side or inlet under the seat.

Ladish Valves globe product line are manufactured as full port, with threaded, socket-weld, flanged and butt weld ends.  Pressure classes include 150 through 1500.  From our Houston, Texas manufacturing facility, we offer valves in the following materials:  CF8M, CF3M, CF8, CF3, CK20, CG8M, CF8C, CN7M, CW12MW, CY40, CW6MC, N12MV, N7M, M35-1, CZ100, CD3MN and many others.
