Masoneilan* 41005 Series Cage Guided Control Valve


The Masoneilan 41005 Series cage-guided, heavy-duty globe valve features balanced trim configurations. This product line offers efficient and stable operation under demanding process conditions, including applications with high-pressure drops and large temperature variations. Optional features include noise attenuation trim, anti-cavitation designs, and various balance seal options to meet a wide range of pressure and temperature requirements.




Features & Benefits

• Balanced trim design allows the use of smaller actuators to reduce overall assembly size and weight
• Heavy cage-guided construction offers dynamic support and trim alignment for resistance against flow-induced vibration throughout the entire valve stroke range
• Heavy guiding of the plug enhances throttling control performance resulting in high process yields
• Low soft-goods parts count for improved valve reliability and reduced maintenance costs
Reliable performance with standard solutions to control noise, cavitation, and valve leakage improving plant operating efficiency

The Masoneilan 41005 Series valve meets the demanding requirements of high pressure drop applications and wide temperature fluctuations. It is designed to handle a broad range of applications across various industries with typical service conditions and operating requirements including:


• Clean and dirty process fluids

• High pressure drop conditions

• High noise gas applications

• Cavitating & flashing liquid applications

• Low temperature and cryogenic applications

The Masoneilan 41005 Series is a highly flexible, field-proven design providing standard balanced trim options within a common valve body platform. Customers benefit by being able to meet a wide range of challenging applications using a single solution.
• Heavy cage-guided construction provides excellent throttling control for reliable plant output
• Various balance seal options covers a wide range of operating pressures and temperatures
• Low emissions packing option reduces external leakage to atmosphere to meet environmental regulations
• Low noise and anti-cavitation trim options effectively reduces the impact to the environment and valve integrity
