WIKA 910.32 Cooling element
Cooling elements are used when the medium temperature would exceed the permissible temperature limit of the pressure measuring instrument. The cooling element can also be used for warming very cold media, provided that the ambient temperature is higher than that of the media. Features: • For medium temperatures up to 200 °C • Can work with pressures up to 600 bar • Connections for G ½ B (EN 837)
WIKA IV1 Needle valve and multiport needle valve
Needle valves and multiport needle valves separate the process from measuring instruments such as pressure gauges, switches or transmitters. By closing this valve the instrument can be safely dismounted for service work like recalibration or replacement. Features: • Low-wear design due to non-rotating spindle tip in the bonnet • Low torque and smooth operation of valve handle even at high pressure • Enhanced safety due to blow-out proof bonnet design • Valve seat tested for leak tightness per BS 6755 / ISO 5208 leak rate A • Customer-specific combination of valves and instruments (instrument hook-up) on request
WIKA IV2 Block-and-bleed valve
The shut-off valve separates the process from measuring instruments such as pressure gauges, switches or transmitters. By closing this valve the instrument can be safely dismounted for services like calibration or replacement. Features: • Low-wear design due to non-rotating spindle tip in the bonnet • Low torque and smooth operation of valve handle even at high pressure • Enhanced safety due to blow-out proof bonnet design • Valve seat tested for leak tightness per ISO 5208 leak rate A • Customer-specific combination of valves and instruments (instrument hook-up) on request
WIKA IV3, IV5 Valve manifold
The 3-valve manifold consists of two shut-off valves and one pressure equalising valve. The pressure equalising valve enables the compensation between ⊕ side and ⊖ side to avoid one-sided overpressure during commissioning and operation. Features: • Low-wear design due to non-rotating spindle tip in the bonnet • Low torque and smooth operation of valve handle even at high pressure • Standardised centre distances of 37 mm and 54 mm • Valve seat tested for leak tightness per ISO 5208 leak rate A • Enhanced working safety due to blow-out proof bonnet design, especially in applications with high pressure loading
WIKA IBM2, IBM3 Monoblock
The monoblock has been designed specifically to fit into the small space of control panel and valve battery installations. The monoblock can be used in a wide range of applications providing high overpressure safety within a large spectrum of temperature ranges. Features: • Increased safety with metal enclosed valve seats and double valve body seal • High-quality machining guarantees smooth operation with low torque and low wear • Leak-tested tightness in accordance with BS 6755 / ISO 5208 leakage rate A • Customisable arrangement with ball and needle valves • Customer-specific combination of valves and instruments (hook-up) on request
WIKA IBF1 Monoblock
The monoblock has been designed to meet the requirements of the process industry, especially for natural gas and aggressive media applications. Features: • The compact design integrates a shut-off valve to separate the process from the instrument side. • For applications with liquid or dirty media, ball valves are recommended due to easy cleaning of the straight-through internal bore. • The one-piece case minimises the number of leakage points and thereby reduces the risk of media escaping into the environment.
WIKA IVM Monoflange
The model IVM monoflange can withstand high overpressures. The valves are suitable for use in critical applications like refineries or steam generation systems. Features: • Compact design with low number of potential leakage points reduces overall weight • Threaded mounting of bonnets not wetted to avoid seizure and leaks • Smooth valve actuation, even under high pressure, leads to fault-free operation and long service life • Metal valve seat with leak-tested tightness in accordance with BS6755 / ISO 5208 leakage rate A • Instrument version for “fugitive emissions” according to TA-Luft and ISO 15848-1
WIKA IBS3, IBJ4 Monoblock
It is especially well suited to applications in natural gas and aggressive media. Features: • Increased safety with metal enclosed valve seats and double valve body seal • High-quality machining guarantees smooth operation with low torque and low wear • Leak-tested tightness in accordance with BS 6755 / ISO 5208 leakage rate A • Customisable arrangement with ball and needle valves • Customer-specific combination of valves and instruments (hook-up) on request
