PERSTA - High-Performance Shut-off Gate Valves for Pressure Isolation

SHARE
PERSTA shut-off gate valves are designed to provide reliable pressure isolation across various demanding applications including chemical and petrochemical industries, industrial and power plant engineering, and shipbuilding. Leveraging decades of experience, these valves boast exceptional sealing capabilities, long service life, and ease of maintenance. PERSTA ensures quality with the use of forged steel manufactured in-house by SIEPMANN-WERKE, which helps achieve high strength, low weight, and a defect-free metal structure. The valves accommodate media such as water, steam, gas, and oil under pressures up to PN 630, with nominal sizes up to DN 1000, and temperatures reaching up to +650°C. Compliance with global standards like DIN, ISO, ASME, EAC, and AFNOR broadens their applicability beyond Germany. A rigorous multi-stage inspection process, from supplier audits to pre-delivery leakage tests, reinforces the valves' high-quality standards.

Shut-off gate valves are the core product in our portfolio. Actively working together with our customers from various sectors, from the chemical and petrochemical industries to industrial and power plant engineering and shipbuilding, means that we have acquired decades of experience.

We are specialists in ‘isolation with no drop in pressure’.

That is why we do not hesitate to make the following claim: Our shut-off gate valves maintain a tight seal for longer, boast exceptionally long operating times and service lives, and are considered to be particularly easy to maintain and service.

When manufacturing pressure-retaining parts, we rely for example on forged steel that has been forged in house at SIEPMANN-WERKE in order to meet our quality standards. This ensures that the metal structure remains free of shrinkage cavities and pores, and has a high strength and low weight. The component wear and volume levels are both extremely low thanks to full seat passage. We can categorically say that the shut-off gate valve from PERSTA is ‘Made in Germany’, but, thanks to numerous certifications and standardisation systems, it is by no means only suitable for the German market. From DIN and ISO to ASME and from EAC to AFNOR, we have extensive experience when it comes to international standards. We rely on multi-stage in-process inspection and quality surveillance, which starts with our supplier audit and ends with the leakage test before delivery, to guarantee permanently high levels of quality.
