E5381

Product catalog summary

General Specifications
The Piston Valve Type E5381 PN16 is designed for dimensions ranging from DN15 to DN200 with a pressure rating of PN16. It features flanged connections with a raised face. The body is made of cast iron, while the internal components are stainless steel. The face-to-face dimensions comply with EN 558:2000 Series 1 (DIN 3202 - F1).

Description
The valve has a reliable self-cleaning construction where the piston slides between two sealing rings. The lower ring is in contact with the media, ensuring that sediments are removed when the valve closes. The sealing ring provides maximum tightness both in the passage and against the atmosphere. It is suitable as a control valve for flow restriction due to its linear characteristic, and it prevents system surges due to its slow opening. The valve is ideal for steam, hot water, hot oil, dry gas, condensate, and varying temperatures. It offers a long lifespan and maintenance-free operation, making it a good investment.

Materials
The valve components are made from various materials: the body and bonnet are cast iron GG25, the handwheel and other parts are steel ST 37, the piston and stem are stainless steel, and the packing is graphite. Other components include brass MS 58 and spring steel.

Dimensions and Flow Coefficient
The valve dimensions and flow coefficients (Kv-values) vary by size. For example, DN15 has a Kv-value of 4.5, while DN200 has a Kv-value of 723. The dimensions include length (L), height (H), and flange dimensions, with weights ranging from 2.9 kg for DN15 to 165.0 kg for DN200.

Pressure/Temperature Ratings
The valve is rated for a pressure of up to 16 bar and can operate within a temperature range from -10°C to 300°C.

A We reserve the right for changes. DESCRIPTION Reliable self-cleaning construction. The piston slides between two sealing rings. The lower ring has media contact on the inner surface - when closing the valve the piston will remove any sediments on the inner surface of the sealing ring. The sealing ring ensures maximum tightness in the passage as well as against the atmosphere. Dansk Ventil Center A/S Suitable as control valve for restriction of flow due to the linear characteristic. Furthermore, system surges are avoided because of the slow opening. Very suitable for steam, hot water, hot oil, dry gas, condensate and varying temperatures. Long life span and maintenance free operation provides a good investment utilization ratio.
