RS350S - Wigersma & Sikkema

RS350S – Pilot operated gas pressure regulator with unique design

The unique design of the new RS350S pilot operated gas pressure regulator offers short response times, high accuracy and stability over a wide flow and pressure range. The pilot has an integrated control system. Because of this the RS350S regulator maintains a stable outlet pressure at varying inlet pressures.

Thanks to its excellent dynamic properties, the RS350S regulator can be used in both distribution stations and industrial installations. The RS350S regulator is manufactured in-house in the Netherlands. This, together with the modular design, results in short delivery times. The RS350S is factory-fitted with a slam shut valve that can be equipped with automatic trip detection. The pressure regulator is designed for “plug & play” installation and delivered with customer-specific settings.

Innovative insert (European patent granted)

The new innovative insert integrates the valve, the valve seat and roller diaphragm into one easy-to-replace module. Maintenance of the pressure regulator and/or change of K_G value can be carried out easily. In addition, the insert can be set-up at the factory so that fit and function is guaranteed on site. The insert can be changed within 15 minutes. The RS350S regulator is available with 5 different valve sizes so that a K_G-range from 185 to 1250 Nm3/h is covered with the DN50 version.

The insert is available separately and comes in a reusablebox that can be used when returning the insert.

The benefits of the pilot operated gas pressure regulator RS350S

When changing the insert, the gas control line is only a quarter of an hour out of operation
Fit and function of the insert can be set-up at the factory/offline
Only a limited number of spare inserts required for maintenance instead of a full range of parts
Changing the K_G value can be done by just changing the insert and is therefore relatively inexpensive
The insert can be overhauled by Wigersma & Sikkema (circular)
Inlet pressure independent
High accuracy and stability
“plug & play” installation
Low noise level

Quality

High quality components are used to ensure corrosion protection. The use of these components significantly extends the lifespan of the pressure regulator. The RS350S regulator can be used without maintenance, depending on the application, for a period of 10 years. All our pressure regulators are manufactured in-house by Wigersma & Sikkema, and adjusted and tested for the specific user application with PLEXOR®, our unique inspection system. Wigersma & Sikkema is renowned for its short delivery times and optimal service.
