Description
The Honeywell V5011N1073 is a 1-1/4-inch two-way threaded globe valve designed for precision control of water, steam, or glycol mixtures (up to 50%) in heating and cooling HVAC systems. It provides 18.7 Cv flow capacity and a direct-acting, stem-down-to-close design suitable for both modulating and two-position control applications. Constructed from red brass with stainless steel trim, the valve ensures durability, corrosion resistance, and smooth flow modulation under demanding system conditions.

Information About V5011N1073
The V5011N1073 is part of Honeywell’s V5011N Series of two-way globe valves, engineered for hydronic and steam service in commercial HVAC systems. The valve is rated for up to 240 psi close-off pressure and supports an ANSI 150 static pressure rating. Its equal-percentage flow characteristic provides stable and accurate water control, while a linear characteristic offers precise steam regulation. Featuring spring-loaded, self-adjusting packing and stainless steel internal components, it delivers long-lasting reliability and minimal maintenance. The valve can be paired with compatible Honeywell actuators such as the ML6420/ML7420, MP953, or via Q5001/Q5020 linkages for Modutrol or rotary motor applications.
Key Features:
- Versatile Media Control: Suitable for hot/chilled water, 50% glycol, or steam service (not for combustible gases).
- Precision Flow Performance: Equal-percentage characteristic for water and linear for steam ensures stable modulation.
- High Close-Off Pressure: Rated to 240 psi, allowing reliable operation in high-pressure hydronic systems.
- Direct-Acting Design: Stem moves downward to close valve, ensuring positive shutoff and control accuracy.
- Robust Brass Construction: Red brass body with stainless steel stem and seat for corrosion resistance and extended life.
- Low Leakage Rate: ≤ 0.05 % of Cv for tight shutoff and efficient system performance.
- Wide Rangeability: 50:1 flow control range per VDI/VDE 2173 provides smooth response across operating conditions.
- Self-Adjusting Packing: Spring-loaded packing minimizes maintenance and compensates for wear.
- Actuator Compatibility: Works with Honeywell ML6420, ML7420, MP953, or Modutrol IV actuators (via Q5001/Q5020 linkage).
- Field Serviceable: Repack and rebuild kits available for quick in-field maintenance.
The V5011N1073 provides dependable, precise flow control in commercial heating and cooling systems requiring durability and fine modulation.
