As our team originally invented envirovalve we know more about stopper containment systems than most and many of our clients ask us for advice on equipment they have.
A recent call for help came in from one of our drainage partners to assist in a pollution release. The site had activated a heavy duty stopper system and the stopper had failed causing a cast manhole cover to be launched several meters into the air, eventually landing on a smoker’s shelter.
Our first job was to assess the risk and viability of stopper system. We found no evidence of any safety valve, in fact, the stopper was the only fail safe we could find. With little left of the stopper we could only conclude that the pressure regulator and pressure switch had failed allowing the stopper to over inflate. With no safe operation, we concluded that the system and its design were unsafe.
The customer immediately instructed us to replace the stopper unit with a Toggleblok™ valve system. Unlike the stopper system, we operate an actuator which does not store enough energy to cause injury in the way an exploding stopper can. All pneumatic systems need to be built and operated safely.
If spill containment and CIRIA736 compliance is currently a consideration for you please do not hesitate to call 01299 823158 or email us, we will be very happy to discuss our solutions with you.

Testimonials
"I was introduced to Sandfield about six years ago when the company I worked for asked me to look at the installation of some new penstock valves and servicing of our pollution control valves across the group sites. After talking to Sandfield and meeting their engineers we gave Sandfield our UK service contract.
We then went on to install Toggleblok valves as we were impressed by how it all worked with a minimum amount of civil work required in most instances.
I have recommended Sandfield Penstock Solutions' Toggleblok to many companies over the last few years. They have a very professional and effective approach to water and waste control systems."
"County Drains have been working with Sandfield for many years.
We have found their knowledge of the Environmental Regulations a benefit to our customers and the products to prevent pollution are second to none."
"Sandfield supply our Company with superior quality equipment and their engineering knowledge has been invaluable during the development of our products. More importantly Sandfield support us by adapting to the many challenging requests we give them and the tight delivery schedules we ask of them."
"Working with Sandfield allowed us to use existing site topography and drainage systems to maximise emergency containment on site, creating meaningful quick response scenario’s which are easily communicated to, and understood by regulatory bodies, emergency services and on site staff. We now satisfy our legal duties set out in our operational permit and under COMAH regulations.
During site operation we have confidence that we are able to cope with emergency situations around the clock. Sandfield Penstock Solutions have installed systems, which are not overly complicated and allow for rapid troubleshooting when faults are found during routine testing and planning for alternative arrangements when issues occur."
"Great product, great installation, what more can I say?"
"We have used Sandfield for well over 30 years. We supply food and pharmaceutical process equipment and as such we must adhere to strict standards for our machinery components.
Sandfield can always be relied upon for a fast, courteous and professional service, the quality of the finished goods are generally very high.
We would have no hesitation in recommending anyone to use Sandfield Engineering."
"Sandfield also have a design facility to cover all aspects of standard and non standard clamping arrangements.
I have always found Sandfield clamps to be robust and cost effective.
Their delivery and technical support is excellent and I have no reservations in recommending them to any manufacturer."
