Steampressurereducing valveworking principle

SCHROEDAHL steam pressure reduction control valves are high-quality products that are fully function-optimized through continuous further development. It was possible to minimize the actuator forces even during high pressure applications, which in-turn leads to the use of smaller and cost saving actuators. The internal construction is designed for low noise operation, which guarantees environmentally- friendly handling. Forged housings combined with a consistent, well thought-out engineering ensures a strong, durable and resistant quality.

Product features - Customised, high-quality steam pressure valve with cage-guided perforated bushing in a single-stage or multi-stage design - For the best handling of difficult operating conditions with high grade pressure control - Low-noise, multi-stage design of the throttle body (perforated bushing) - Screwed cover or self-sealing design Features and advantages Pressure reduction via multi-stage controlled, sub- critical expansion is particularly low-noise. - The valve seat and perforated basket can be replaced - Large control ratio for control in the start-up range with high differential pressure - Low-maintenance, adjustable stuffing box (packing pure graphite) Options: - Balanced plug - Armoured sealing surfaces - Heating and drainage nozzles Designs according to customer requirements are also available. All common drive types can be used.
