About Durbin Industrial Valve
What industries does Durbin Valve specialize in?
Durbin Valve supports industries where pressure and temperature control directly affect production quality and safety. These include tire and rubber manufacturing, chemical processing, food and beverage operations, energy applications, and general industrial manufacturing. These environments often involve high heat, elevated pressure, and continuous cycling that standard valves struggle to handle over time.
What makes Durbin Valve different from other valve suppliers?
Durbin Valve combines accurate, pressure-tested valves with direct access to engineers who understand real process conditions. Fast fulfillment programs and upgrade options like New-for-Old help reduce downtime and planning delays. Customers work directly with people responsible for valve design and support, not layered sales channels.
What types of valves does Durbin Valve manufacture?
Durbin Valve manufactures control valves, regulating valves, 4-way directional valves, swing check valves, Y-style body design valves, and more. Each product focuses on stable control, repeatable performance, and long service life in industrial environments.
How quickly can Durbin Valve ship replacement valves?
Stocked valves and assemblies can ship within 48 hours. For non-stock items, in-house manufacturing and streamlined production allow delivery faster than typical industry lead times.
What is the New-for-Old Exchange Program?
The New-for-Old exchange program provides a brand-new, current-design valve at the same cost as repairing an older unit. Instead of rebuilding worn components, the entire valve is replaced. This approach shortens turnaround time, improves performance immediately, and reduces the risk of repeat failures.
Can Durbin Valve customize valves for specific applications?
Yes. Durbin’s engineering team regularly modifies valves to meet application-specific pressure, temperature, media, and connection requirements. This approach helps solve plant-specific challenges that off-the-shelf valves often cannot address.
What support does Durbin Valve provide after installation?
Customers have direct access to Durbin’s engineering and support teams for troubleshooting, installation guidance, diagnostics, and performance questions. Support continues well beyond installation to help maintain stable operation and address issues early.
Valve Terminology and Definitions
What is a globe valve?
A globe valve is used to regulate flow within a pipeline. It uses a movable plug or disc that seats against a stationary ring inside a spherical-shaped body. Flow control occurs as the plug moves toward or away from the seat. Globe valves may be manually operated or automated through pneumatic, hydraulic, or electromechanical actuators.
What is a spool valve?
A spool valve, also known as a directional valve, controls fluid flow by shifting a spool inside a cylindrical body. The spool contains lands and grooves that block or allow flow. These valves direct fluid through different paths and are commonly used in hydraulic and pneumatic systems.
What is a check valve?
A check valve allows fluid to flow in only one direction and prevents backflow. It operates automatically without external control. Common check valve types include ball, diaphragm, swing, lift, and in-line designs, each suited for specific flow and pressure conditions.
What is a control valve?
A control valve regulates fluid flow by adjusting the size of the flow passage based on a signal from a controller. This adjustment allows direct control of process variables such as pressure, temperature, and liquid level. Control valves may use pneumatic, electric, hydraulic, or mechanical actuation.
What is an on-off valve?
An on-off valve, also called an isolation valve, opens fully or closes fully without regulating flow. These valves are commonly used to isolate systems during maintenance or troubleshooting and may be manually or automatically actuated.
What is a three-way valve?
A three-way valve has three ports and directs flow based on how it is piped and actuated. It may act as a diverter or selector depending on application requirements.
What is backflow prevention?
Backflow prevention refers to stopping fluid from flowing upstream against the intended direction. Check valves are commonly used for this purpose to protect equipment and maintain system stability.
What is a valve seat?
At Durbin Valve, the seat refers to the stationary surface where the moving seal or disc makes contact to stop flow. The seat is typically harder than the sealing component.
What is a valve stem?
The valve stem transfers force from the actuator to the sealing element. It passes through the valve body and is sealed to prevent leakage.
What is a valve body?
The valve body houses the internal components that control fluid flow. It includes inlet and outlet ports and affects pressure and temperature capability.
What is a valve gland?
The gland, sometimes called the bonnet, seals around the valve stem and connects the stem assembly to the valve body.
