CRANE PRESSURE TEST POINT T84

CRANE PRESSURE TEST POINT T84

P84 insertion style pressure test points are fitted as standard to Crane FS flow measurement and regulation valves. Pressure test valve P82 is suitable for use in LTHW and MTHW systems. A conventional needle valve, operated by a standard radiator aircock key, is backed by a spring loaded self-sealing ball unit to provide double sealing. The double sealing facility offers maximum operational safety in accordance with the Health & Safety at Work legislation. It also makes it possible, with the valve closed to pipeline pressure, to clear the ball seat of any pipeline debris. Although P82 is also suitable for use in HTHW systems it should not be operated while such a system is ‘live’. For ‘live’ HTHW systems copper bleed tubes should be taken from the valves and terminated in needle valves, eg. Crane D71 or D72. The manometer connection on the valve accepts a Mechseal adaptor. When not in use a screw cap protects the connection from dust.
