Valves used for throttling services have always been subject to rapid deterioration in the form of erosion, cavitation damage, and wiredrawing of vital parts. Even venturi valves and other special configurations are vulnerable.
• Dual range throttling - primary range plus a super capacity blast range.
• Rapid energy dissipation - controls the destructive forces inherent in high pressure drop service.
• Accurate and repeatable settings - micrometer dial assures setting accuracy and positive resetting capability. • Quick-change disc - insert an interchangeable stem-disc into the same valve body to convert from one orifice size to another.
• Guided-disc - eliminates disc vibration and chatter.
