Cooled make-up water control valves

Detailed product information

The valve has a multi-stage throttling system, and the cellular throttling unit combined with a needle valve allows it to withstand significant pressure drops. The valve seat has an independent conical seal that provides reliable sealing, and in combination with an unbalanced valve, zero leakage is achieved. All internal components are made of surface-hardened stainless steel, resistant to erosion and have a long service life. The relative reduction in pressure drop at each stage expands the control range, especially at low flow rates, maintaining good control capability. The pressure drop at each stage is controlled within critical limits, eliminating cavitation and flashing. The sleeve and valve have an optimal clearance and are equipped with a guide sleeve with good guiding properties for smooth operation. The valve has flexible control and precise regulation.

Product application

Steam cooler systems, steam superheaters, and intermediate superheaters for boilers. Low-pressure bypass steam cooling systems. Water supply systems for steam cooling in reduction and cooling units, pressure regulators. This valve provides low flow control, has a wide control range, and operates smoothly.
