What is a Forged Globe Valve?
With its forged body construction, the globe valve maintains its shape even under high pressure and temperature, while its non-spherical (disc-and-seat) design enables gradual flow regulation. As a result, it provides stable, low-vibration and safe control in both on/off and throttling duties. The forged material enhances grain structure, impact resistance and tightness performance.
Technical Features and Materials
Forged globe valves can be manufactured from carbon steel, low-alloy steel, stainless steel and nickel alloys. Depending on the application, different disc/seat combinations (hard-faced surfaces, Stellite overlay), guided disc, cage-guided trim or reversible disc solutions can be selected.
On the actuation side, manual handwheel, electric, pneumatic or hydraulic actuators are available. EMS Valve offers robust, easy-to-maintain trim designs tailored to your process requirements.
Standards, Testing and Certification
EMS Valve products are designed and tested in line with major international standards according to your project requirements. Design and manufacturing can be carried out under ANSI/ASME, API or PED frameworks; acceptance and pressure tests are performed in accordance with API 6D, API 598 or customer-specific standards.
For non-destructive examination, MSS SP-55 visual inspection, penetrant testing, magnetic particle testing, ultrasonic and radiographic testing can be applied. Additional assurance is provided through ISO 17025 accredited laboratory capabilities and ISO 9712 qualified personnel.
Advantages and Fields of Application
- Precise flow control: Stepwise throttling with a near-linear control characteristic
- High tightness: Machined seating surfaces for low leakage
- Forged body strength: Security against thermal shock and pressure fluctuations
- Ease of maintenance: Top-removable trim and accessible internal parts
- Wide application range: Power, refinery, chemical, petrochemical, marine and process industries
EMS Valve combines decades of manufacturing discipline with engineering simulations and modern workshop capabilities to deliver stable performance even in the most demanding process conditions.
Installation, Maintenance and Operation Recommendations
During installation, observe flow direction and valve orientation; support the pipeline properly to avoid unnecessary vibration. During operation, slow opening and closing manoeuvres help extend the life of the seating surfaces.
In periodic maintenance, do not neglect packing inspection, stem surface cleaning and disc/seat cleaning. Under severe service conditions, keeping spare trim components in stock will help to minimise downtime.
Typical Application Scenarios
- Heating plants and energy centres: Stable control in condensate return and by-pass lines
- Power plants: Throttling and balancing in steam lines
- Refineries & petrochemical plants: Control of high-temperature and corrosive media
- Chemical plants: Precise dosing and reactor feed lines
- Marine and shipbuilding: Safe control in fuel and auxiliary system lines
