Pneumatic sleeve control valve

Application
They are used as an executing element in the instrumentation
and remote control systems to control the liquids, vapours and gas flow.
The wide range of material versions, advantageous operating pressures and temperatures, numerous design variations matched to the process requirements are a reason the valves shall be used at the most heavy-duty conditions in power and heat engineering, petrochemical and chemical industry, metallurgy,etc.
Characteristics
 Various material versions of the valve cast and internal parts, matched to the specific operating conditions
 Designs reducing the generated noise level, increasing the cavitations and flashing resistance, eliminating choked flow
 A wide range of pressure ratings from PN 10 through PN 420, as well as of the flow coefficients and of the control characteristics
 Reduced emission of aggressive and toxic fluids into the environment due to the bellows seal or compression gland corresponding to TA-LUFT regulations being observed
 Easy disassembly and installation of the valve internal components for the purpose of inspection and service
 Long life and operating reliability due to high quality materials being used and to the surface improvement techniques (burnishing, stelliting, heat treatment, CrN coatings)
 An ability to cooperate with multi-spring actuators P1/R1 (cast yoke) and P/R (column) of totally reversible operation, as well as a possibility to vary the spring range - with no extra parts (the number of springs unchanged)
 A possibility to fit the actuators with a lateral (P1/R1) or a top (P/R) manual drive
 Diagnostic possibilities for the „valve-actuatorÿ?system due to the intelligent electro pneumatic positioners being used
 A wide range of electric drives
 Special versions available
1. for oxygen
2. for liquid and gas fuels
3. for low temperature fluids (liquid oxygen, nitrogen)
4. or acid H2S-containing gasses
5. with a heating jacket
6. service at flammable conditions acc. to directive 94/9/EG - ATEX
7. The product designing and manufacture are in compliance with the specifications of the quality
 management system ISO 9001, of the directive 97/23/EG and of AD 2000 Merkblatt regulations
