WIKA 910.12 Pressure gauge snubber
The pressure gauge snubber is adjustable (modification of the crosssectional flow) and can thus be adapted individually to the respective operating conditions. Features: • Max. temperature 120 °C • Nominal pressures up to 400 bar
WIKA 910.15 Syphons and connecting pipes
U-form syphons are intended for horizontal pressure tapping; trumpet-form syphons are intended for vertical pressure tapping. Features: • Compact version suitable for vibration applications • Customer-specific combination of valves and measuring instruments (instrument hook-up) on request • Permissible temperatures to 550 °C [1,022 °F] • Nominal pressures to 420 bar [6,091 psi]
WIKA 910.14 Gauge adapter
Male-female gauge adapters are used where the size of the male thread is different from the female thread in the parts to be connected. Female-female gauge adapters are used where both components to be connected have male threads. Male-male gauge adapters are used where both components to be connected have female threads. Applications: • For the mounting of pressure measuring instruments, gauge cocks, shut-off valves, pressure gauge syphons, snubbers and other accessory components.
WIKA 910.18 Case protector
The model 910.18 case protector is fitted to the pressure gauge before mounting. Features: • Use enables a longer service life of the instruments • For nominal sizes 50 [2"], 63 [2 ½"], 80 [3"] and 100 [4"] • For instruments with radial or back mount connection locations • Simple fitting
WIKA 910.22 Pressure Gauge In-Line Filters
Grade of filtration200 μm Temperature range-25 … +200 °C Operating pressureDepends on the sealing washer the customer uses: • Sealing element PTFE: PN max. 100 bar • Sealing element stainless steel 1.4571: PN max. 1,600 bar Features: • They avoid: • Plugging of small gauge pressure entries and capillary throttles • Accumulation of particles in dirt-sensitive gauge interiors and its consequences • Furthermore they have an effect of a throttle and damp shock pressure
WIKA 910.21 Pre-volume deflagration flame arrester
The model 910.21 pre-volume deflagration flame arrester enables the mounting of pressure measuring instruments and diaphragm seal systems in areas with requirements to EPL Ga (zone 0). Features: • Fulfils the requirements of flame arresters in accordance with EN ISO 16852 • With ATEX and IECEx approval
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
