Comprehensive Solution For Steam And Heat System

Thermostatic bimetallic Steam Trap

Steam trap is a device that can automatically remove non-condensable gases such as steam condensed water and air in heating equipment or steam pipes, with no steam leak.

Thermostatic (bimetal) Steam Trap are characterized by large subcooling, long life, good energy-saving effect, water hammer resistance, and beautiful appearance. They are widely used in heating and steam transporta-tion pipelines.

The technical advantages of VMV traps are: unique and reasonable structure and high-precision internals!

High Strength Corrosion Resistance

Using A105 material, the corrosion allowance, minimum shell wall thickness, pressure and temperature grade are fully considered in the design.

Imported Bimetal

U.S. imported bimetallic sheet to ensure specific bending value, adjustable temperature structure, precise temperature control.

Linear Sealing Closure System

Unique linear sealing closing system and micron-level high-precision valve seat and valve core ensure reliable closing and o steam leakage

Built-in Filtering Device

Effectively prevent pipeline impurities from entering the valve, ensure the normal operation of the trap,and prevent water hammer from damaging internal components.

Structural Features

VMV thermostatic (bimetal) Steam Trap body and bonnet are made of A105, and the condensate discharge temperature can be adjusted. It has been adjusted to 120-130℃ when leaving the factory.

Thermostatic (bimetal) Steam Trap adopts a line-sealed shut-off system without original steam leakage, noise, good air discharge ability, fully utilizes the sensible heat of condensate water, and has a good energy-saving effect.

Thermostatic (bimetal) Steam Trap works on the temperature difference between steam and condensate. When the condensed water in the pipeline stays in the pipeline due to the high temperature, the temperature of the energy to be released will decrease when the bimetal deforms and the valve seat opens to discharge the condensed water. Users can adjust the discharge temperature of the trap at any time according to the season.

The material of the valve body and bonnet of the bimetal steam trap is ASTM A105, the bimetal is imported materials, the rest of the internal parts are stainless steel, and with built-in filtering device.

Selection and Installation of Bimetal Steam Trap

The bimetallic trap continuously drains water. Normally, the discharge temperature of SHT16 is 120-130℃, and the discharge temperature of SHT32 is 140-150℃ (users can adjust it). If there is any requirement for supercooling, please indicate when ordering. The back pressure rate of the bimetal trap can reach 50% (back-end pipeline pressure/steam pressure), which is not suitable for closed recovery systems, but is suitable for pipelines and heating systems to remove condensate. In general, the safety factor is 2-3 times.

Warm reminder: The condensed water volume and pressure difference of steam equipment are important indicators for type selection. The displacement of the same type of trap increases as the pressure difference increases. Please check the displacement curve in detail. Please don't mistake it for a large-diameter trap with a large displacement.

The bimetal trap can be installed at any position in the pipeline or equipment. The basic configuration of the trap is shown in the figure above.
