Description
WLD600 Series — Float Type Liquid Drainers
The WLD600 Series Float Type Liquid Drainers are designed for applications where immediate and continuous discharge of large volumes of liquid is required. These high-pressure, high-capacity liquid drainers are commonly used in industrial process systems for draining condensate from air or other gases. The float-operated valve provides a modulating flow characteristic for smooth, efficient liquid removal. All models are built for durability and feature a stainless-steel internal mechanism housed in a carbon steel body.
Reliable High-Pressure Liquid Draining
The WLD600 Series is engineered to withstand demanding process conditions, offering maximum operating pressures up to 450 PSIG depending on the connection type and flange class. The float mechanism automatically adjusts to liquid level changes, ensuring uninterrupted drainage without air binding or steam loss. These units are ideal for continuous-duty industrial applications where consistent liquid removal is essential.
Material Specification
- Body: Carbon Steel
- Internals: Stainless Steel
Technical Specification
- Sizes: 3/4", 1", 1 1/2", 2", 3", 4"
- Connection: Threaded (NPT), Socket Weld (SW), Flanged (150# / 300# / 600#)
- Maximum Operating Pressure: up to 450 PSIG (varies by flange class)
Operating Principles
Liquid entering the WLD600 Drainer raises the internal float, opening the discharge valve and allowing condensate or process liquid to exit the unit. As the liquid level drops, the float lowers and throttles the valve to maintain controlled discharge. This automatic modulating action ensures reliable, efficient drainage under varying load conditions, making the WLD600 ideal for high-capacity industrial processes.
