HP Control Valves for Urea Service CV-870U

Valve Series CV-870U & CV-870S were specifically developed to satisfy the high reliability and the best performance required in urea and melamine plants; experience gained in the field, fluid-dynamic feature optimization and the use of specific materials allow the obtaining of high resistance to erosion and to corrosion in presence of particularly aggressive process fluids even at high pressure and temperature values.

Our valve design also takes into consideration easy assembly and disassembly of internal parts to facilitate maintenance operations.

Upon request, valves can be provided with electrically traced jackets or jackets with diathermic fluids to heat valve body at the required temperature. Flushing ports are often provided to clean valve trim, in order to avoid crystallization and deposit, granting superior reliability.

The actuator and instrumentation provided with the valve are carefully selected and calibrated to ensure the best control performance.
