Product Details

The VERSA QE-3-316 is a 3-way, 2-position normally closed (NC) Quick Exhaust Valve designed for pneumatic applications. It is installed directly at a cylinder port connection to provide rapid exhaust of compressed air and help achieve faster movement of a pneumatic cylinder rod or valve actuator. (Versa Valves)

The valve features 316L stainless-steel construction and is specified by VERSA as conforming to NACE MR-01-75, making it suitable for demanding industrial and sour-environment applications when the complete system is appropriately specified. (Versa Valves)

Description

The VERSA QE-3-316 Quick Exhaust Valve is a compact pneumatic valve designed to improve actuator response by providing a direct, large exhaust path.

A conventional pneumatic control arrangement may require exhaust air to travel back through the control valve. The Quick Exhaust Valve provides a dedicated exhaust path close to the cylinder, allowing compressed air to be released rapidly.

The VERSA QE-3-316 uses a three-port configuration consisting of an inlet port, cylinder port and larger exhaust port. When inlet pressure is applied, the exhaust is closed. When inlet pressure is lost, the cylinder-side air can exhaust through the larger exhaust passage. (Versa Valves Selector)

This makes the QE-3-316 particularly useful where fast pneumatic cylinder or actuator movement is required.

Important: Confirm the exact port configuration, seal material, pressure, temperature and media compatibility against the manufacturer's documentation before ordering for a critical application.

How Does the VERSA QE-3-316 Work?

The QE-3-316 has three ports:

Inlet → Cylinder → Exhaust

During pressurization, inlet pressure closes the exhaust path and supplies the cylinder.

When inlet pressure is removed, the cylinder-side pressure causes the valve to open the exhaust path. The air can then discharge through the larger exhaust outlet instead of travelling back through the upstream pneumatic control valve.

Result: reduced exhaust restriction and potentially faster pneumatic cylinder or actuator movement. (Versa Valves Selector)

Applications

The VERSA QE-3-316 can be considered for applications such as:

Pneumatic cylinders
Pneumatic actuators
Process control equipment
Industrial automation
Manufacturing machinery
OEM machine building
Oil & gas equipment
Chemical processing equipment
Marine applications
Pneumatic valve actuators
Equipment requiring rapid actuator response

For hazardous, sour-gas or other critical-service applications, verify the complete valve specification and system compatibility with the manufacturer before installation.

Why Use a Quick Exhaust Valve?

A Quick Exhaust Valve can be useful when a pneumatic actuator needs to move faster and the exhaust path through the directional control valve is creating excessive restriction.

The VERSA QE-3-316 places the exhaust function close to the actuator, providing a larger and more direct exhaust route.

Typical benefits

Faster cylinder response
Faster actuator movement
Reduced exhaust restriction
Direct cylinder-port installation
Compact pneumatic circuit arrangement
Stainless-steel construction for demanding environments
