| 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. |
- wide range of nominal dimensions, DN15…150 for nominal pressures PN10…40; CL150; CL300
- various materials of valve body cast and internal parts, adapted to specific working conditions
- wide range of flow coefficients
- reduction in aggressive and toxic media emissions to the environment through application of 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 P/R multi-spring actuators (basic option), P1/R1. Full reversibility of actuator operation and changing the spring range with no extra parts
- optional fitting of pneumatic actuators with manual drive
- possibility of performing diagnostics of “valve-actuator” system due to application of smart electro-pneumatic
- positioners
- high tightness of closure due to the application of soft valve seats (with PTFE seals in the whole range of flow coefficients
- same flow ratios and control characteristics for “hard” (metal-to-metal)
- and “soft” (metal-gasket) seats
- reliable connection between actuator stem and valve, as well as between screwed in seat and body,
- top-class flat and bonnet packings
- wide range of electric actuators,
- possibility of matching with 20 or NN type manual drives
- possibility of special executions: for oxygen, hydrogen, 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
