Product Description
G90 Bronze safety relief valves – side outlet discharge with lifting lever
These valves are commonly used for preventing a safe pressure being exceeded in pressurised systems. The lift is proportional to the system overpressure. Particularly suitable for most liquid applications where a ‘small’ discharge often prevents the safe pressure in a system being exceeded. Also suitable for steam, gases & vapour applications where a low discharge is suitable.
- Male Inlet x Female Outlet.
- Inlet: Threaded ‘G’ BSP Male to BS EN ISO 228/BS 2779
- Outlet: Threaded ‘Rp’ Parallel Female to BS 21/BS EN 10226/ISO 7
- Alternative thread standards, i.e. BSPT or NPT are available upon request.
- Flanged connections also available. Most flange standards can be accommodated.
- Gresswell Valves are quality assurance approved to BS EN ISO 9001: 2015 and manufactured in accordance with BS EN ISO 4126-1 & BS6759.
- Full Cat IV PED approval.
- Only 4 springs are needed to cover the full pressure range.
- Clear operating and maintenance instructions are supplied with each despatch.
- Screwed/Flanged or a combination of both are available as standard.
- See data sheets for Discharge Capacities.
