Why choose the Hemiwedge® Cartridge Valve for your Processing application?  Here’s a perfect example:  

Situation:  A customer needs an emergency shutdown valve to replace leaking metal-seated ball valves in a skid.  The existing valves have been prone to frequent, expensive, time-consuming repair due to particulates in the service fluid. Other rising stem valve options are too tall and will not fit in the skid.

Solution:  The Hemiwedge® Cartridge Valve is selected for a variety of reasons: mechanically seated design for maximum performance in service fluids with particulates; ability to provide appropriate hard-facing option; ability to replace trim quickly and easily (if needed); protected seat seals in full open position; low emissions; and an actuator with a spring-assist option to provide additional closing thrust in the final closing action as the closure member wedges into the seat.

Features:

• Mechanically-loaded seal
• Wide range of elastomeric and non-elastomeric seat seals for suitability with various fluids
• Metal-To-Metal Seat Option
• No lubrication required
• Full bore with aligned body-core-seat for pigging
• All trim contained in one replaceable, pre-tested cartridge
• Available in ANSI 150-900 Class  
• Quarter-turn operation

Processing Application Opportunities:

• Gas Separation Systems
• Safety Shutdown Valve
• Emergency Shutdown (ESD) Valve
• Dehydration Switching
• Block Isolation Valve
• Ethylene Shutoff
• Butylene Shutoff
• Propylene Shutoff
• Compressor Block Valve
• Sour Gas Shutoff
