VST10 – FLOAT & THERMOSTATIC STEAM TRAP
VST10 is a premier Float & Thermostatic Steam Trap engineered for continuous condensate drainage and rapid air venting. Its combined float and thermostatic mechanism efficiently removes condensate and non-condensable gases while minimizing live-steam loss to the atmosphere.
DESCRIPTION
Meticulously designed with an innovative float-and-thermostatic-capsule arrangement, VST10 supports stable condensate removal across varying steam loads. Its water-seal concept, integral strainer and robust internal structure provide excellent resistance to demanding steam-system conditions and support maximum operational reliability.

VST10 – FLOAT & THERMOSTATIC STEAM TRAP FAQ
When should I consider VST10 instead of VDT10 for a steam project?
VST10 is a float-and-thermostatic trap suited to applications that prioritize continuous condensate discharge together with rapid air and non-condensable gas venting. VDT10 uses a thermodynamic disc mechanism and may be preferred where a compact, simple trap is more suitable. Final selection should reflect the actual steam application.
What size, orifice and connection options are available for VST10?
VST10 provides orifices from 0.7 mm to 5 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 can be supplied for VST10?
The listed body material options include A216-WCB, A351-CF8M and A890-4A. Bronze and Super Duplex series are available on request.
What information should be provided for VST10 technical selection?
Steam pressure, differential pressure, expected condensate load, connection size and type, material requirement and the intended steam application are useful for selecting the appropriate configuration.
