THERMAL SHUT-OFF VALVE (TSV)
The Manvia Thermal Shut-off Valve (TSV) is an essential mechanical safety device designed to protect online analyzers and personnel from high-temperature excursions. In the event of a cooling water failure or a primary cooler malfunction, the TSV automatically trips and shuts off the sample flow when the temperature exceeds a pre-set limit (typically 50°C). Unlike electronic solenoids, this valve is completely mechanical and self-actuated, ensuring fail-safe protection even during total power loss at the plant.

HIGH PRESSURE REDUCER VALVE (HPRV)
The Manvia High Pressure Reducer Valve (HPRV) is a precision-engineered component designed to handle the most demanding pressure reduction tasks in steam and water analysis systems. Unlike standard regulators, the HPRV utilizes a sophisticated rod-in-tube or multi-stage orifice design to provide stable, adjustable, and noise-free pressure reduction from supercritical levels down to safe operating ranges. It is built to withstand high velocity and potential flashing, ensuring long-term reliability and constant flow rates for downstream analytical instrumentation.

BACK PRESSURE RELIEF VALVE (BPRV)
The Manvia Back Pressure Relief Valve is a critical component for maintaining constant upstream pressure within the sampling line. By providing a stable "back pressure," it ensures that flow rates to sensitive online analyzers remain consistent regardless of fluctuations in the process or cooling water demands. Designed with high-sensitivity diaphragms, the BPRV also acts as a safety relief, venting excess sample flow to the drain if pressure exceeds the set limit, thereby protecting delicate sensors from over-pressurization.
Technical Requirements:

ISOKINETIC SAMPLING PROBE
The Manvia Isokinetic Sampling Probe is the critical first point of contact in a Steam and Water Analysis System (SWAS). Specifically designed to meet ASTM D1066 and ASME PTC 19.11 standards, this probe ensures that the steam sample extracted from the main header is truly representative of the bulk flow. By maintaining isokinetic conditions—where the velocity of the steam entering the nozzle matches the velocity of the steam in the pipe—it prevents the common issue of phase separation, ensuring accurate measurement of impurities and chemical concentrations.
Technical Requirements:
- Standards: Compliance with ASTM D1066 / ASME PTC 19.11

TCU COOLING WATER TEMPERATURE CONTROL UNIT
The Manvia Temperature Control Unit (TCU) is a sophisticated thermal management system designed to regulate the temperature of the cooling water itself before it enters the sample coolers. By maintaining a constant and chilled cooling water supply, the TCU ensures that the final sample temperature remains strictly at 25°C, even in tropical climates or environments with high ambient fluctuations. This "primary regulation" layer is essential for high-precision analytical systems where even a 1°C deviation can affect conductivity or pH accuracy.
Technical Requirements:
