DriSteem 505086-003 Fill Valve

The DriSteem 505086-003 Fill Valve is a critical 24VAC solenoid valve assembly engineered for precise water level management in DriSteem humidification systems, including the GTS, GTS-LX, and STS series. This OEM replacement part features a rugged body design capable of handling high-temperature environments and variable water pressures common in commercial HVACR applications. Operating on a 24V water inlet valve configuration, it ensures reliable flow modulation to prevent dry firing of heat exchangers and maintain optimal steam production efficiency. As a technician, you know that keeping a genuine DriSteem repair part on hand minimizes system downtime during critical heating cycles. This valve is designed for a direct-fit installation, utilizing standard NPT connections to ensure a leak-free seal and compatible electrical termination with existing DriSteem control boards. Replacing a fouled or sticking valve with a new 505086-003 restores factory-spec water level control and protects your equipment's longevity.

• OEM Compatibility: Exact DriSteem 505086-003 match ensures seamless integration with the existing control logic and mounting brackets.
• Precise Flow Regulation: Optimized for the specific GPM flow rate requirements of high-output humidifiers to eliminate short-cycling.
• Standardized Electricals: Operates on a standard 24V circuit, allowing for straightforward diagnostic testing with a multimeter.
• Durable Construction: Built to withstand the scaling and mineral buildup often encountered in commercial humidification water lines.

Is this fill valve compatible with the GTS-400 series?
Yes, this valve is the designated OEM replacement for various GTS and STS models. Always verify the part number in your specific unit's technical manual as configurations can vary by production year.

What causes these valves to fail prematurely?
Failure is typically caused by debris in the water inlet or mineral calcification on the plunger. Installing an inline strainer can extend the service life of the solenoid seat.

Can I use an aftermarket 24V valve instead?
While third-party valves may fit the thread, they often lack the specific pressure rating and orifice size required for DriSteem's precise fill rate logic, potentially leading to tank overfills or low-water alarms.
