DRV Steam pressure reduction valve

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.

    Benefits

    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.
