Arrotop is a solid manufacturer and supplier of Three Valve Manifolds in an H‑Type, flange-to-flange configuration. Designed for seamless integration with inline pressure transmitters and gauges, this advanced assembly features block, equalizing, and vent valves in a compact H‑style layout to ensure safe and efficient instrumentation control.
With flange connections on both the inlet and outlet, the H‑Type design guarantees structural stability and minimizes leak risk, making it ideal for high-pressure, process-critical systems.



What is a Direct Mount H Type Three Valve Manifold (Flange × Flange)?
A Direct Mount H‑Type Manifold includes:
- Two flanged connections (inlet and outlet) for direct inline installation
- One block valve to isolate the instrument
- One equalizing valve for pressure balancing during calibration
- One vent/bleed valve for safe depressurization
This configuration enables direct inline installation of transmitters or gauges, requiring no external tubing or brackets, and supports complete control, isolation, equalization, and venting, on-site.
Key Features
- Full three-valve assembly: isolation, equalization, and vent
- Flange × Flange configuration (ANSI/ASME/BS or ISO standards)
- Rated for pressures up to 6,000 psi, tested at 5× proof pressure
- Constructed from materials like 316/316L SS, Carbon Steel, Duplex, Monel, Hastelloy
- Non-rotating stem tip and blowout-proof stem provide consistent sealing performance
- Multiple packing options (PTFE, graphite, specialty compounds)
- Compact and corrosion-resistant H‑Type bar design
