Product Details

The Siemens 270-03185 is a 2-way normally-closed pneumatic control valve assembly designed for HVAC hot and chilled water applications. This complete assembly combines a 1-inch Flowrite globe valve with a 4-inch pneumatic actuator for precise flow control in commercial building systems.

Key Specifications:

  • Valve size: 1-inch female NPT (FxF) connection
  • Flow coefficient: 10 Cv (8.6 Kvs)
  • Valve action: 2-way, normally-closed (NC)
  • Valve trim: Bronze/brass construction
  • Characteristic: Equal percentage flow
  • Actuator size: 4-inch pneumatic actuator
  • Spring range: 10-15 psi operating pressure
  • Base valve: 599-03185
  • Base actuator: 599-01083

This valve assembly is part of Siemens Flowrite 599 Series and provides reliable, proportional control for hydronic systems. The normally-closed configuration ensures the valve closes when air pressure is removed, making it ideal for fail-safe applications. The equal percentage flow characteristic provides excellent control at partial loads, which is common in HVAC systems.

Ordered a fuel line, came in a little late but was fedexs fault, good customer service definitely will work with them in the future

Awesome site

Good service and quick shipping. Arrived in 1 to 2 days.

So far so good. Hurry up and ship these to me!

all good

Lights look good, very bright, however they did not fit properly in the factory openings. They were about 3/8' too short from mounting point to round opening. I did some modification and made them mount on the bottom side of the bumper flat instead of the top. I removed the factory lights and compared them and could visibly see the difference.

Quick and easy

Good price...fairly quick delivery
