MANIFOLD VALVES

A Manifold Valve is a specially designed, jacketed three way valve. The Manifold Valve consists of two hand
operated valves, which open normally, and one pneumatically actuated valve, which closes normally. Together
with our Angle Valve, the Manifold Valve is installed on the process line coming from the urea reactor.

The Manifold Valve operates at approximately 150 Bar at a temperature of +180°C.

Merwede’s Manifold Valve is designed and developed back in the 80’s. In close cooperation with OEM of N/C
metering skids the Merwede’s Steam jacketed Manifold Valves to serve the demanding urea plants “N/C”
metering systems.

Since the 80’s the Manifold Valve was more fine-tuned on the design and actuation, which led to the latest
design of this type of valve.
