The York S1-9951-0981 Orifice is a precision-engineered OEM component designed for specific gas manifold configurations within York

High Conductivity: High-performance copper and brass conductors maximize current flow while maintaining cooler operating temperatures

and gas-fired combustion systems

Durable Construction: High-grade copper tubing prevents premature failure from thermal expansion

if the signal falls below the module's threshold

ASCO 8210G95HW-24V Solenoid Valve 30067439-890 The York S1-9951-0981 Orifice isThe ASCO 8210G95HW 24V is a high performance 2 way normally closed solenoid valve specifically engineered for demanding hot water service applications. Featuring a robust brass body and a 3 4 inch NPT connection, this pilot operated valve utilizes a durable EPDM diaphragm to handle fluid temperatures up to 210F. Operating on a 24Vac power supply, it delivers a high flow capacity with a 5 Cv rating and functions reliably within a 0 100 PSI pressure
