Valve Manifold Boxes


DownloadButtonIn semiconductor, pharmaceutical, and chemical processing applications, custom valve boxes or cabinets are often needed. These can be required for safety, leak detection monitoring, or security reasons. The boxes come in all sizes and shapes. They can be made of regular polypropylene or fire retardant FM4910 rated materials to eliminate or restrict fire and smoke damage.

Each box can have a variety of manifolds, different door designs and door hardware (clear plastic or solid), sensors mounted for leak detection and an integral electrical panel for alarms and controls. They can have manual, pneumatically actuated or electric solenoid valves. Special stem configurations can allow emergency shutoff without opening the cabinet.

Wastech Controls will design and fabricate custom process valve boxes for your exact needs. Our shop can work with thermoplastics or stainless steel.

Tank Fill Stations
