Everything you need to know about Globe Solenoid Valves

Globe valves offer precise throttling for high-pressure systems and are ideally suited for the most demanding process applications that have a wide range of temperature extremes. PIF looks at their practical uses, as well as the pros and cons of installing such a solution.

What are Globe Solenoid Valves?

Globe Valves are so called because of their spherical body shape. Also occasionally known as the 'Up and over Valve', this versatile Valve is used for regulating flow in frequent and throttling operation applications.

An opening inside the body forms the seat on to which the disc is screwed to close the valve. This has a slightly higher pressure drop than straight through valves – like a ball or gate valve – if it is used for on/off duty. Globe valves are uni-directional and must be installed in the correct flow position.

Advantages and disadvantages of Globe Solenoid Valves

Globe valves have many advantages and disadvantages. One of the pros is their precise throttling for high-pressure systems. The cons include low-flow coefficients and a longer operating time because the operator is required to manually turn the handle and stem repeatedly to ensure that the valve is fully opened or closed.

Applications for Globe Solenoid Valves

Globe valves are ideally suited for the most demanding process applications. They can be used in systems that call for frequent stroking, vacuum, and systems that have a wide range of temperature extremes. Globe valves can be used for gas and liquid systems. They are not recommended for high purity or slurry systems because inherent cavities promote contamination and allow slurry material to become trapped. This can disable the valve's operation.

Key Manufacturers of Globe Solenoid Valves

ASCO's 2-way piston operated solenoid valve valve assembly, with HS series position indicator and solenoid pilot valve, is a cost effective alternative to an actuated ball valve assembly. This linear on/off valve is a stand alone solution that can be used in a variety of applications. Versatile, proven, and reliable, the 8290 series process valve is available in Bronze or Stainless Steel and all components are backed and manufactured by ASCO.

Bürkert's Type 2101 is a 2/2-way Globe Valve with stainless steel design for media up to +185°C that is combinable as an On/Off System Type. In line with Bürkert’s philosophy for modular valves and sensors the construction of the 2101 globe valve fulfils tough criteria for process environments. Unrivalled cycle life and sealing integrity is guaranteed by the proven self adjusting spindle packing with V-seals.

The design enables the easy integration of automation modules whether they are electrical/optical position feedback, pneumatic control units, or an integrated fieldbus interface. The fully integrated system has a compact and smooth design, integrated pneumatic lines, IP65/67 protection class and superior chemical resistance.

Globe Solenoid Valve Materials

Globe valves are widely available in a range of metal and alloy constructions, and plastics, to cover a wide spectrum of industrial applications. Proper material compatibility is dependent on the type, concentration and temperature of the media.
