Globe Valve Manufacturer in Germany

Globe valves are linear motion valves used where a piping system requires dependable isolation together with controlled flow regulation. The internal seat and disc arrangement creates a defined throttling path, allowing the flow rate to be adjusted more progressively than with valves intended primarily for full open or full closed service.

Flow Regulation Through Linear Disc Movement:

A globe valve regulates flow by moving the disc or plug in a linear direction toward or away from a stationary seat.

As the stem rises, the opening between the disc and seat increases and allows more fluid to pass through the valve. Lowering the disc reduces the available flow area until the seat is fully closed.

This linear movement makes globe valves suitable for:

• Flow throttling
• Process regulation
• Frequent operation
• Steam control
• Cooling-water regulation
• Isolation where controlled closing is required

T-Pattern, Y-Pattern and Angle Body Designs:

The body configuration determines the internal flow path and influences pressure loss, installation arrangement and throttling performance.

• Y-Pattern Globe Valve
• Angle Globe Valve

Plug, Needle and Composition Disc Options:

Disc geometry influences shut off behaviour and flow control capability.

Disc Types:

• Plug Type Disc: Provides controlled throttling through progressive seat engagement.
• Needle Type Disc: Enables precise regulation of low flow rates.
• Composition Disc: Uses a replaceable non-metallic seat for tight shut-off.
• Metal Disc: Suited to higher-temperature, abrasive or demanding service.

Stem, Bonnet and Seat Construction:

The stem transfers motion from the handwheel, gearbox or actuator to the disc.

Rising-stem configurations provide visible valve-position indication and are commonly used in industrial process systems.

Bonnet arrangements can include:

• Bolted bonnet
• Welded bonnet
• Pressure seal bonnet
• Bellow seal bonnet arrangements

A pressure seal bonnet is typically used for higher pressure and higher temperature systems where internal line pressure assists the bonnet sealing arrangement.

Bellow seal globe valves incorporate metallic bellows around the stem to provide an additional containment barrier for applications where external stem leakage must be minimized.

Seat rings may be integral, renewable, threaded or welded depending on the valve design.

Pressure Drop and Throttling Performance:

Globe valves inherently create more flow resistance than straight-through isolation valves because the fluid changes direction while passing through the seat area.

The resulting pressure drop should therefore be considered during valve sizing.

Important factors include:

• Flow rate
• Available differential pressure
• Fluid density
• Required Kv or Cv
• Operating temperature
• Valve opening
• Fluid velocity
• Cavitation potential in liquid service
• Noise in steam or gas service

Actuation and End Connections:

• Operation: Handwheel, gear, pneumatic, electric or hydraulic actuator.
• Automated Control: Pneumatic and electric actuators suit remote or process-control systems.
• Flanged Ends: Easy installation and removal across industrial pipe sizes.
• Butt Weld Ends: Used for high integrity welded piping.
• Socket Weld Ends: Suitable for smaller bore, higher pressure lines.
• Threaded Ends: Common for smaller sizes and suitable pressure ranges.
• Selection: Match the connection to the piping class, pressure rating and applicable EN or ASME standard.

Steam and Process Flow Applications:

Globe valves are widely used where flow must be isolated or adjusted repeatedly.

Typical applications include:

• Steam distribution
• Boiler feedwater systems
• Power generation piping
• Cooling water systems
• Chemical processing
• Petrochemical plants
• Process-fluid control
• Marine piping
• Condensate systems
• Industrial utility networks

For steam and high temperature systems, body material, bonnet construction, trim material and packing should be matched to the operating conditions. For corrosive process media, stainless steel, Duplex, Super Duplex or special alloy constructions can be selected according to fluid compatibility.
