Engineering Excellence & Design Details

High-Strength Diaphragm Cartridge Assembly

The core of the ST900 trap features a diaphragm made from high-grade Hastelloy C276 alloy. This critical component is assembled using advanced vacuum-welding techniques within the pressure capsule, ensuring exceptional fatigue resistance, zero leakage, and reliable operation over millions of cycles under fluctuating pressures and temperatures.

Integrated Stainless Steel Strainer

Each unit is equipped with a built-in, high-quality stainless steel strainer. This integrated filter effectively prevents pipeline debris, scale, and other particulates from reaching and clogging the precision valve seat, thereby ensuring consistent performance and reducing maintenance needs.

Precision Diaphragm Disc with Spherical Seal

The sealing mechanism employs a unique spherical disc integrated with a hardened G10-grade chrome steel ball. This design guarantees a perfect, wear-resistant seal by meeting the most stringent requirements for sphericity and micro-surface finish, virtually eliminating steam loss.

Discharge Capacity Performance

The MATICA ST900 series is engineered for high-efficiency discharge across its operational range. The discharge capacity charts (available in the technical downloads) detail the precise kg/h rates for models DN15 to DN25 under various pressure differentials. This data is essential for engineers to correctly size and select the optimal trap for each specific application, ensuring system harmony and peak efficiency.
