RS350S - Wigersma & Sikkema

RS350S – Pilot operated gas pressure regulator with unique design

The unique design of the RS350S gas-operated pressure regulator results in fast response times, high accuracy and excellent stability across a wide flow and pressure range.
The pilot regulator features an integrated pre-pressure control, making the regulator inlet pressure independent – the outlet pressure remains stable even with fluctuating inlet pressures.

Thanks to its excellent dynamic performance, the RS350S is suitable for use in both distribution networks and delivery stations.
Production in the Netherlands, combined with the modular design, ensures short delivery times.
The RS350S is supplied as standard with a safety shut-off valve (SSV) and can be equipped with a shut-off signalling module for additional safety and control.

An optional silencer can also be installed, reducing the sound level of the regulator by approximately 8 dB.

SSV shut-off signalling

To further enhance the safety and reliability of gas distribution systems, Wigersma & Sikkema has developed a SSV shut-off signalling module for the RS350S regulator.

This module makes it possible to remotely detect whether the safety shut-off valve (SSV) has been activated. It provides additional assurance during operation and simplifies remote monitoring and maintenance.

Key features:

Available with Namur or Reed sensor
Rugged design and easy installation
Reliable indication, even in case of cable break or vibration

Innovative insert (patented)

The insert integrates the valve, valve seat and rolling diaphragm into one easily exchangeable module.
This provides major advantages – maintenance and changing the flow capacity (KG value) can be performed quickly and easily.
Each insert is factory tested, ensuring correct functionality in the field. Changing the insert takes only 15 minutes.
The RS350S is available with five different valve sizes, covering a KG range of 185 to 1250 Nm³/h for the DN50 regulator.
The insert is supplied in a reusable box, which can also be used for returning the insert for overhaul.

Main advantages:

Only 15 minutes downtime when changing the insert
Factory-tested functionality
Reduced spare parts stock – only a few inserts required
Easy and cost-effective KG value change
Circular overhaul possible via Wigersma & Sikkema
Inlet pressure independent control
High accuracy and stability
Low noise and easy “plug & play” installation

Quality and reliability

Only high-quality components are used in the RS350S to ensure excellent corrosion protection and long service life.
Depending on the application, the regulator can operate for up to 10 years without maintenance.

All gas pressure regulators are tested and adjusted to customer specifications using PLEXOR®, our unique inspection system.
Wigersma & Sikkema is known for short delivery times and excellent service.

Adapters for the RS350S

With the adapters for the RS350S it is possible to easily replace other (old) regulators with a different inlet and outlet side (e.g. RMG 402 and 408) with the RS350S.

Here are some possibilities (other lengths or sizes are available on request):

As the RS350S is very compact, it can be used as a replacement for various other (obsolete) gas pressure regulators without having to change the gas pressure regulation system. The installation dimension of the DN50 version of the RS350S is only 230 mm!
