At Roosevelt Valves, we understand that the most efficient industrial systems start with reliable components. That’s why the Z221-A2M-OO, a 2-way, normally closed, direct-acting solenoid valve, has become one of the most versatile solutions in our catalog for general-purpose applications.
Engineered for Demanding Environments
The Z221-A2M-OO is constructed with a brass body and stainless steel internal components, ensuring excellent corrosion resistance. Thanks to its direct-acting design and floating diaphragm made of Nitrile (NBR), this valve does not require minimum pressure to operate—making it ideal for low-pressure or medium-vacuum systems.
Key Applications
Its compatibility with a wide variety of fluids—such as water, air, neutral gases, low-viscosity oils, and steam—makes it suitable for sectors such as:
- Welding equipment
- Dental autoclaves
- Water treatment systems
- Laundry and dry-cleaning machines
- Instrumentation systems
Technical Specifications That Make a Difference
- Maximum allowable pressure: 150 PSI
- Connection: 1/8” NPT
- Kv (flow rate): 0.14 m³/h
- Temperature range: 14°F to 284°F (with EPDM seal)
