Indicator Valves

AS-Schneider Indicator Valves Type S473 and Indicator Valves Type N473 are available with a lot of possibilities. Indicator valves are based on the need to measure and monitor cylinder pressures in large-bore diesel engines and natural gas engines as well as gas compressors. The robust design of the valves gives long service life and optimum operating comfort. The AS-Schneider Indicator Valves Type S473 and Type N473, as standard, are rated to 300 bar (4,351 psi).

Indicator Valve Type S473:

AS-Schneider Indicator Valve Type S473 is available with a lot of options. Indicator valves are based on the need to measure and monitor cylinder pressures in large-bore diesel and natural gas engines and gas compressors. The core of the Indicator Valve Type S473 is the spring-loaded needle tip. This long established design prevents the valve from being opened due to engine vibration. It also allows smooth operation even at high-temperature service. Supplied c/w heat-protected handle alternatively with a removable T-Handle Key. The valve body is die-forged.

Max. allowable (Working) Pressure (PS): 300 bar (4,351 psi)

Bore Size: 0.236" (6 mm)

Indicator Valve Type N473:

The indicator valve type N473 allows a reduced installation radius at limited space. The valve opens "against engine pressure" and closes "with engine pressure." Any movement of the valve stem due to engine vibration tends to tighten the valve stem upon its seat thus eliminating the possibility of opening under operating circumstances. The valve body is die-forged.

Max. allowable (Working) Pressure (PS): 300 bar (4,351 psi)

Bore Size: 0.197" (5 mm)
