Bestobell Cryogenic Bronze Globe Valve

Bolted Bonnet – Extended Stem and Non Extended Stem
DN6 – DN50 (¼” – 2”)

Bronze extended and non extended stem globe valves with bolted bonnet, integral seat and renewable PTFE disc, complete with bronze internals. Available with screwed ends, the valve is of the cone seat design for drop tight shut off. The bolted bonnet allows easy maintenance, even in confined spaces with lower bolting torques required than for the equivalent size union bonnet valve. All valves are degreased for oxygen duty, assembled in clean room conditions and pressure tested prior to dispatch.

Bestobell Bronze Relief Valve

DN15 – DN32 (½” – 1 ¼”)

Maximum Working Pressure

40bar at -196˚C to +65˚C

[/ezcol_1half]

[ezcol_1half_end]

 

A range of high quality bronze relief valves designed to comply with ISO 4126 (“Safety Valves General Requirement”), BSEN 13648-1 safety valves for cryogenic service. They are eminently suited to the protection of static and road going cryogenic storage tanks against damaging over pressure. There are three basic sizes, defined by the throat diameter, 11.4mm, 14.0mm and 20.5mm and each is available with a variety of inlet and outlet connections. See details under technical data. The valve is designed and factory set to lift repeatedly within 2% of the set pressure, and to reset above, 92% of set pressure. Spring pre compression and blow down ring settings are sealed after test to inhibit unauthorized tampering. Flow-rates at 10% above set pressure are measured to ensure compliance with stated flow capabilities.

Features and Benefits

A lift-limiting stop helps prevent valve instability when discharging from or into the lengthy piping runs that can be characteristic of cryogenic systems, though good piping practice should still be observed when installing these valves. An optional lifting lever/manual override is available on request. Each valve is individually set and flow tested and then stamped with the date of manufacture and its own unique serial number prior to dispatch. All valves are degreased for oxygen duty, assembled in clean room conditions, and sealed in robust polythene bags prior to
dispatch.
