D/A Manufacturing provides a complete line of instrument valves and manifolds including: differential pressure valve manifolds, pressure transmitter and gauge valve manifolds, multi-port gauge valves, block valves and accessories.
- Dial-A-Function® – A new generation of manifolds that reduce downtime caused by human error (improper positioning or sequencing of the valves). Dial-A-Function® automatically positions and sequences the valves to help protect the transmitter from damage and the plant from inaccurate measurement control.
- Safti-Fold® – The safest, most dependable and durable line of instrument manifolds and valves. Safti-Fold® valves help protect the plant, process, operator and environment from process blowout, uncontrollable leakage and non-operation.
- General Purpose – A completely new line of superior designed manifold valves. This valve features bottom-loaded spring packing, which controls fugitive emissions and leaks. The bonnetless valve assembly eliminates safety hazards due to broken off or unscrewed bonnets. An ultra-hard ceramic-to-metal seat eliminates ball creasing and seat galling.
