Thermodynamic Disc Steam Trap
The VALMERU VDT10 Thermodynamic Disc Steam Trap is designed for reliable condensate discharge in steam mains, tracing and other industrial steam applications. Its compact single-moving-part disc mechanism reduces mechanical linkages and wear points while delivering reliable condensate discharge for steam mains, tracing and demanding industrial steam service.
DESCRIPTION
Using the thermodynamic velocity and pressure effects of flash steam, VDT10 discharges cool condensate and air during start-up and then cycles automatically as operating conditions change. Its rugged, compact construction is designed for demanding environments including water-hammer, superheat and low-temperature exposure.

VDT10 – THERMODYNAMIC DISC STEAM TRAP FAQ
When should I consider VDT10 instead of VST10?
VDT10 uses a compact thermodynamic disc mechanism and is commonly suited to applications such as steam-main drainage and tracing where a simple, robust trap configuration is preferred. VST10 is generally better aligned with applications that prioritize continuous condensate discharge and rapid air venting.
What size, orifice and connection options are available for VDT10?
VDT10 provides orifices from 0.7 mm to 8 mm depending on differential-pressure class, with body and connection sizes from 1/2 inch (DN15) to 2 inch (DN50). NPT, Socket Weld and ANSI flange connections are available.
What material options are available for VDT10?
The listed body material options include A216-WCB, A351-CF8M and A890-4A. Bronze and Super Duplex series are available on request.
What information is useful when requesting a VDT10 quotation?
Steam pressure, differential pressure, condensate load, intended application, connection size and type, and required material are useful for technical selection and quotation review.
