Rupture Disc Accessories
Excess flow valves are expertly designed to prevent pressure build-up in the space between the rupture disc discharge and the second safety device. As rupture discs function as differential pressure devices, it is crucial to avoid pressure accumulation to ensure proper disc activation at the specified bursting point. Excess flow valves are typically employed in conjunction with rupture discs and safety valves, or when multiple rupture discs are arranged in series. These valves automatically close when subjected to the flow from the rupture disc discharge. Available in ¼” and ½” sizes, excess flow valves can also be customised with T connectors, nipples, and pressure gauges upon request. All accessories for rupture discs are manufactured from high-quality stainless steel.

Hattersley Fig MH733 PN16 Double Regulating Valve
Features & Benefits
• The double regulating feature enables the valve to function for isolation and can be reopened to its preset position, thereby ensuring the maintenance of the required flow rate.
Specifications
• Y-Pattern globe valve equipped with a characterised throttling disc and flanged ends conforming to BS EN 1092-2 PN16. • The valve opening can be adjusted to control flow at a predetermined rate. • Operation of the valve is facilitated by a hand wheel that includes a position indicator. • An ANSI version is also available (MHA733).
Pressure/Temperature Rating
• 16 bar pressure rating from -10 to 120ºC. • Ratings comply with BS EN 1092-2 PN16 standards.
CONCOA 492 Series Regulator
Six-port, chrome-plated brass, single-stage regulator for ultra-high pressure applications
The CONCOA 492 Series regulator delivers primary pressure control for non-corrosive gases in high-purity, ultra-high-pressure applications. Instead of a diaphragm, it employs a robust piston assembly to safely manage extreme inlet pressures. Factory-installed options allow configuration as a single-station manifold, with or without purge, low-pressure alarm, or multiple inlets.
