Festo GR Series Flow Controller Flow Valve, 3720

Festo Series GR Flow Valve, 10 Bar Maximum Operating Pressure, Die Cast Zinc - GR-1/2, Numeric Part Number: 3720

This flow valve regulates pneumatic flow in industrial control systems and is intended for use where controlled Air movement is required. Constructed from die-cast zinc, it is designed to operate across a wide ambient temperature range and is suitable for general-purpose automation and machine integration.

Features & Benefits

• Maximum working pressure 10 bar provides robust system control
  Operates from -20°C to +75°C for varied environmental conditions
  Minimum functional pressure 0.1 bar enables low-pressure responsiveness
  Die-cast zinc construction offers mechanical durability and longevity
  Designed as a pneumatic flow control valve for precise flow adjustment

**Applications**

• Suitable for machine automation pneumatic circuits in factories
  Ideal for control panels requiring flow regulation under fluctuating temperatures
  Used with actuators to moderate Air supply and motion speed
  Can be used for testing rigs where low-pressure control is necessary

What material is the valve body MADE from and why does that matter?

The valve body is manufactured from die-cast zinc, which provides a solid balance of strength and dimensional stability for repetitive mechanical installations.

What pressure conditions will allow correct operation?

It will function effectively at system pressures up to 10 bar while remaining responsive at pressures as low as 0.1 bar, covering both medium- and low-pressure pneumatic requirements.

How does temperature affect deployment choices?

The operational capability from -20°C to +75°C permits installation in cold storage areas and heated production environments without derating performance.

Is this product intended for hazardous-area installations?

It does not carry hazardous-area certification, so it should not be specified for classified explosive atmospheres.
