Specifications:
The direct-activated pressure reducing valve is constructed from Stainless Steel 316, making it suitable for fluid, air, and steam applications. It features a balanced-pressure gate design to maintain consistent outlet pressure despite fluctuations in inlet pressure. The valve requires a pressure of 1.5 kgf/cm² to transition from fully closed to fully open.

Performance and Design:
The valve's design includes a piston and diaphragm to enhance pressure sustainability and minimize leakage. It offers a pressure adjusting range of 1-6 kgf/cm², 4-10 kgf/cm², and 8-13 kgf/cm², with a conversion of 1 kgf/cm² equaling 14.2 psi. The valve operates effectively within a temperature range of -15 to 85°C.

Testing and Pressure Limits:
The valve body is tested at a pressure of 35 kgf/cm², with a maximum applied pressure of 25 kgf/cm². It is recommended to cover steam pipelines with thermal materials. Special orders can accommodate higher pressure adjustment ranges.

Materials and Components:
Key components include a pressure gauge, upper cover, piston, shaft, main body, and lower cover made from Stainless Steel 316. Other materials used are NBR, Viton, Teflon for seals, and Stainless Steel 304 for fixed bolts and adjusting stems.

Dimensions and Models:
The document lists various models with their respective sizes, dimensions (H and L in mm), weight (kg), and flow coefficient (CV). For example, model RETI15-S is 1/2” in size, with dimensions 75mm x 71mm, weighing 0.9 kg, and a CV of 2.4.
