LESER S&R safety valve
|
Products advantages |
|
|
n Their greater proportional range leads to a constant mode of operation and relief of pressure peaks for liquids in particular. |
|
|
n compact construction and low weight for easy handling. |
|
|
n identical construction for steam, gasses and liquids (single trim) reduces the number of required spare parts and facilitates cost-effective maintenance. |
|
|
n construction without a blow down ring guarantees easy service and prevents incorrect settings of the blow down ring. |
|
|
n LESER Nanotightness: Exceeds the tightness requirements of API 527 by 50%. |
|
|
n Are approved by all important approval organizations world-wide which ensures the worldwide applicability e.g. |
|
|
n the one-part spindle reduces friction, guarantees optimal guidance and reliable operation under all operating conditions. |
|
|
n One design and spring (single trim) for steam, gas and liquid applications reduces the number of spare parts and ensures low cost maintenance management. |
|
|
n the self-emptying angle type body prevents residue and reduces corrosion. |
