| Non-catalogue products
| We can adjust these parameters to your individual needs. In such cases, please contact our technical support specialist. In the menu: “Non-catalogue version control valves” and “New products” we present the following examples. |
- range of nominal sizes from DN15 to DN250 for pressure values PN10 to CL300
- various materials of valve body cast and internal parts, adapted to specific working conditions
- wide range of 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 P/R (column) multi-spring actuators and changing the spring range with no extra parts (keeping the number of springs)
- possibility of fitting actuators with top drive
- possibility of performing diagnostics of “valve-actuator” system due to application of smart electro-pneumatic positioners
- high tightness of closure due to application of soft valve seats (with PTFE seals in the whole range of flows and characteristics, for valve plugs, balanced and unbalanced)
- same flow ratios and control characteristics for “hard” valve seats (metal-to-metal) and “soft” valve seats
- (metal-to-gasket), for valve plugs, balanced and unbalanced
- reliable actuator-stem and valve seat-body connections
- small guiding sleeve control forces due to application of balanced valve plugs in valves DN40…250
- top-class flat and bonnet packings
- wide range of electric actuators
- possibility of matching with NN type manual drives
- possibility of special executions: for oxygen, hydrogen, gas fuels; low temperature mediums (liquid oxygen, liquid nitrogen), acid gases containing H2S; for explosive atmospheres as per 94/9/EC – ATEX
- competitive prices – as a result of a simple and functional design of valves and actuators, as well as applied materials
- 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
