Pressure safety valves

PRESSCON develops and produces safety valves for vertical and horizontal buffer tanks used in heating or cooling systems.
These safety valves are used to protect buffer tanks against vacuum or excessive pressure.
Our safety valves operate entirely mechanical and are therefore unsusceptible electricity outages.
The PRESSCON pressure and vacuum valves are produced using RVS (AISI 304) making them highly durable and weather resistent. For special situations the pressure valves can also be specified with other materials such as RVS 316 and/or different sealant materials.

PRESSCON safety and vacuum valves are designed and produced entirely in-house, and can be specified for the exact desired pressure settings.
Our safety and vacuum valves have a modular design that facilitates easy maintenance and can be optionally specified with integrated heating elements for cold water storage tanks in sub-zero environments.
Our safety and vacuum valves can also be specified for use with Biogas storage tanks, and we can deliver any desired size and pressure settings the project may require.
We distinguish two types of safety valves:

  • Vacuum, work and relief valves (mainly vertical buffer tanks)
  • Vacuum safety valves (horizontal buffer tanks)

Advice and custom solutions

All our products are designed, built and tested in our own factory in Honselersdijk and are characterised by innovation, efficiency and quality.
With both design and production being done in-house, our organisation and products have a high level of flexibility.
This enables us to build and deliver custom installations for the specific challenges and requirements of each project, that go beyond our standardised product line-up.

After Sales:

We offer various maintenance models on the basis of an hourly rate or in the form of a maintenance contract, both within the Netherlands and internationally.
We’ve strived to constantly perfect our product design, in order to simplify maintenance operations and we also provide thorough documentation and trainings for customers that wish to do maintenance themselves.
With our 24/7 service department, we support our customers day and night in case of malfunctions.
