Description
Blocking and draining instrumentation valves are standard when using dual valve sets. The blocking valve separates the process from a measuring instrument such as a pressure gauge, switch or transmitter. By closing the valve, the meter can be safely removed for recalibration or replacement of the meter. The drain valve safely drains instrument waste before disassembly or zero check.
The spindle head is not rotatable to reduce wear on the sealing element. This also significantly extends the life of the product, especially when it is frequently turned on and off.
Valves are designed with explosion protection to improve their work safety, especially under high pressure loads.
WIKA can perfectly fit valves and pressure gauges and incorporate this service and other accessories into a direct-install solution, also known as a connection. To ensure the performance of the entire system, leak testing is also performed when making connections.
