Benefits & Features
The KM1 is a 3-valve manifold designed for applications where direct mounting to an instrument is impractical or undesirable. This style manifold is mounted to the lines from the instrument and signal rather than directly to the instrument; a KMC Mount is also available. These manifolds are often used in conjunction with small differential pressure indicators, recording orifice meters, etc., that have connections other than the standard 2-1/8" (54 mm) distance between taps. A 3/16" (4.8 mm) orifice is provided. The standard manifold has integral metal seats, and soft seats (roddable) are available in various materials. |

Benefits & Features
The KM4AP and KM4TP are two-valve, block and bleed style manifolds. These manifolds are intended for static pressure applications and are generally used with Differential Pressure (DP) style pressure transmitters. The block valve isolates the instrument (normally a transmitter) from the process and is normally open in service. When the block valve is closed to isolate the instrument, the bleed valve may be opened to safely vent pressure from the instrument. The KM4AP design permits the process signal line from the transmitter's futbol flange to be connected directly to the manifold. The KM4TP design has a standard 1/2-inch FNPT inlet connection. |

Benefits & Features
The KMP1 is a two-valve manifold used primarily for single instrument applications such as test, calibration, block and bleed, and instrument zeroing. The KMP1 functions both as the manifold valve and also as the mount for the instrument, all in the same unit. The KMP2 manifold provides the same functions as the KMP1 except two different instruments may be installed simultaneously and both supplied from a single pressure source. It has dual block and bleed valves serving the exact same functions as the KMP1 manifold, except for two instruments rather than one. The KMP2 manifold also serves as the mount for two instruments. The pressure instruments are connected to either manifolds via 1/2-inch FNPT or 1/2-inch MNPT union connectors. |
