Details

Detail image
Balanced double seat: Featuring an innovative balanced dual-seat design, this trap significantly reduces the force required to open the valve. This allows for a compact unit that delivers a condensate capacity 3-4 times greater than conventional single-seat models.
Detail image
Built-in air vent assembly: The trap is equipped with a versatile, serviceable air vent assembly (available in thermostatic or bimetallic variants). During cold start-up, the integrated automatic air vent opens to rapidly evacuate air and condensate. This feature boosts discharge capacity, ensuring faster equipment heat-up.

About ST400 series by MATICA

Engineered for Excellence: The MATICA ST400 Series – Your Ultimate Defense Against Steam System Inefficiency

For industrial operations in Turkey where steam is the lifeblood of production, protecting your system from energy waste and physical damage is not just a priority—it is an economic imperative. LİNDER ENDÜSTRİ DIŞ TİCARET LİMİTED ŞİRKETİ, as the official and authorized dealer of MATICA premium industrial valves in Turkey, brings you the engineering solution designed to meet this critical challenge head-on: the MATICA ST400 Series High Capacity Ball Float Steam Trap. This is not merely a component; it is a system safeguard engineered for unmatched reliability, durability, and performance in the most demanding Turkish industrial applications.

Uncompromising Protection for Critical Industrial Assets

The MATICA ST400 is engineered to be the stalwart guardian of your steam infrastructure. Its core mission is to provide unparalleled protection for critical steam systems, directly combating the two arch-enemies of operational efficiency and profitability: catastrophic energy waste and destructive water hammer. By ensuring the immediate and automatic discharge of condensate under pressures up to a formidable 40 bar, it guarantees three fundamental outcomes for your plant:

Operational Reliability & Steam Dryness

Consistent, high-quality dry steam for your sensitive processes, eliminating the risk of product defects and ensuring repeatable, high-quality output.

Extended Equipment Lifespan

Proactive protection of capital-intensive assets—boilers, heat exchangers, turbines, and dryers—from thermal stress, corrosion, and erosion caused by stagnant condensate.

Sustained Process Temperature & Energy Efficiency

Optimal heat transfer efficiency, ensuring precise process temperatures, maximum throughput, and minimal thermal energy loss, directly impacting your bottom line.

Trusted by leading Turkish enterprises across key sectors, the ST400 is the specified choice for safeguarding vital equipment including shell & tube heat exchangers, heating batteries, industrial autoclaves, process pans, drying cylinders, and thermal ovens.

A Paradigm of Advanced Engineering: Beyond Conventional Steam Trap Design

What sets the MATICA ST400 apart in the Turkish market is its incorporation of patented, innovative features that translate into tangible operational superiority and rapid return on investment.

Balanced Double-Seat Technology for Maximum Capacity

At the heart of the ST400 lies an innovative balanced dual-seat design. This engineering breakthrough dramatically reduces the actuator force required to open the valve mechanism. The result is a remarkably compact unit that delivers a condensate discharge capacity 3 to 4 times greater than conventional single-seat traps. This means you can handle higher loads with a smaller footprint, optimizing both plant space and capital expenditure.

Integrated & Serviceable Air Vent Assembly

Peak system efficiency begins at startup. The ST400 is equipped with a versatile, in-line serviceable air vent assembly (available in thermostatic or bimetallic variants). During cold start-ups, this integrated vent opens automatically to rapidly purge air and cold condensate. This feature drastically improves initial heat-up times, boosts overall system discharge capacity, and ensures your equipment reaches operational temperature faster, saving both time and substantial energy from the very first minute of operation.

Proactive Inlet Runner Design for System Integrity

Understanding the destructive potential of water hammer, MATICA engineers have incorporated a dedicated stainless steel baffle within the inlet port. This component actively dampens hydraulic shock and mitigates damaging pipeline vibration before it can affect the trap’s internal mechanism, offering an essential layer of protection for the entire downstream steam system and reducing maintenance costs.

Built to Endure: Premium Materials for the Demanding Turkish Industry

The ST400 is a testament to durability, designed for the long haul. It utilizes high-strength, precision-welded stainless steel floats capable of withstanding significant hydraulic shock and corrosive elements. Available in a comprehensive range of body materials including Cast Iron (GGG40), Carbon Steel (WCB), and Stainless Steels (CF8, CF8M), it is engineered to match your specific service environment—from aggressive chemical plants to high-temperature textile mills. Critical internal components, such as seats and discs, are crafted from hardened steels (A276 420, 440C), while seals and gaskets utilize robust combinations like 304/316 stainless steel with graphite, ensuring long-term, leak-free performance and minimal total cost of ownership.
