- various materials of valve body cast and internal parts, adapted to specific working conditions
- constructional designs limiting the level of generated noise, increasing resistance to cavitation and flashing, enabling elimination of throttled flow
- wide range of nominal pressures from PN10 to CL2500, as well as flow ratios and control characteristics
- reduction in aggressive and toxic media emissions to the environment through application of bellow seal bonnets or bonnet packings meeting the requirements of TA – LUFT
- easy assembly and dismantling of valve internal parts for maintenance and service
- high durability and reliability due to application of top-class materials and surface improvement processes (burnishing, stelliting, heat treatment, CrN coatings)
- possibility of matching with reversible action P1/R1 (with cast yoke) and P/R (column) multi-spring actuators and changing the spring range with no extra parts (keeping the number of springs)
- possibility of equipping the actuators with a side (up to P1/R1) or top (up to P/R) manual drive
- possibility of performing diagnostics of “valve-actuator” system, due to application of smart electro-pneumatic positioners
- wide range of electric drives
- - possibility of special executions: for oxygen, hydrogen, low temperature mediums (liquid oxygen, liquid nitrogen), acid gases containing H2S; with heating jacket; for explosive atmospheres as per 94/9/EC – ATEX
- the design and production process meet the requirements of Quality Management System ISO 9001 and Directive 97/23/EC, and regulations of AD2000 Merkblatt, designated for installation on pipelines
- easy assembly and dismantling of valve internal parts for maintenance and service
- high durability and reliability due to application of top-class materials and surface improvement processes (burnishing, stelliting, heat treatment, CrN coatings)
