Our commitment to you
Manufacturing and quality
Spirax Sarco controls are designed and manufactured by
Spirax Sarco in one of 15 manufacturing plants located
around the world. We also have dedicated fabrication facilities
so we can build compact, high performance, skid mounted
solutions tailored to your specific requirements.
All Spirax Sarco facilities employ the latest in technology and
production best practice, to ensure we have direct control
over our product and service quality.
Product quality
Assembly is automated, testing is computerised and every
controls product and system is set using skilled personnel
to ensure a consistently high quality. For example every
Spirax Sarco control valve receives a computerised hydraulic
pressure test at 1.5 times the nominal rating of the valve,
and the shut-off is tested to ensure it complies with the class
specified. Over 100 separate checks are carried out on a
control valve assembly before it is despatched.
Sizing and selection software
Correct product selection and system design is key to
achieving good performance and long service life. Depending
on the process conditions this can be a complex decision.
In order to allow our engineers to make these decisions
quickly and reliably Spirax Sarco has developed its own
software systems to ensure you achieve the best price
performance from your investment.
Severe service applications
Suitable for applications that have high pressure-drop
requirements, aggressive process conditions or media. These
applications may require special materials of construction or
use an energy dissipating disc stack system.

QA systems, health and safety requirements,
insurance needs, environmental policies and an
increasing risk of litigation, have all increased the
amount of documentation needed to support our
