MAMAC Systems VM-706 Manifold

The MAMAC Systems VM-706 is a 3-valve manifold engineered specifically for technical professionals managing wet-to-wet differential pressure applications. Constructed from high-grade 316 stainless steel, this isolation/null manifold ensures superior media compatibility and long-term durability in demanding HVACR and industrial environments. The VM-706 features an integrated pressure equalization valve and two high-pressure isolation valves, allowing for precise zero-calibration and maintenance without stripping the entire system. Designed with a 6000 PSIG pressure rating and standard 1/8" FNPT process connections, it facilitates a robust, leak-proof interface for differential pressure transmitters like the PR-282 series. The compact footprint and monolithic pressure cavity design eliminate common failure points such as welds or O-rings, providing the reliable bubble-tight shut-off required for process instrumentation and fluid flow monitoring. This stainless steel manifold is the industry standard for field technicians prioritizing NIST traceable accuracy and system integrity.

• High-Pressure Reliability: Rated for up to 6000 PSIG to handle extreme hydraulic and pneumatic surges.
• Corrosion Resistance: Full 316 stainless steel wetted parts provide compatibility with various liquids and gases.
• Simplified Maintenance: The 3-valve configuration allows for easy zeroing of sensors and isolation of instruments.
• Leak-Proof Design: Rugged monolithic construction minimizes leak paths and simplifies HVACR piping layouts.
• Precision Control: Precision-machined bonnet and stems prevent galling, ensuring smooth operation under high torque.

What is the primary function of the equalization valve on the VM-706?
The equalization (null) valve allows a technician to balance the pressure between the high and low ports. This is critical for performing a static pressure zero adjustment on a differential pressure transmitter without disconnecting the process lines.

Can this manifold be used in steam applications?
Yes, provided the operating temperature stays within the 0° to 180°F range. For higher temperature steam, use a pigtail syphon to protect the manifold and sensor from direct thermal shock.

Does the VM-706 support NPT or flare connections?
This model utilizes 1/8" FNPT (Female National Pipe Thread) connections for both the process and instrument sides, ensuring compatibility with standard industrial fittings.
