5-Way valve manifold is used for differential pressure transmitter. The typical 5-way valve manifold consists of 2 block valves, 1 equalizer valve, and 2 vent or test valves. If we want to check the zero of the transmitters, we just need to close the block valve and open the equalizing valve. If we want to calibrate the transmitter for 3- or 5-point calibration, then after the pressure is equalized, we just need to connect the test valve to a pressure generator. This 5-way valve manifold is the most common valve manifold for differential pressure transmitter.
Features
- One Piece Bar Stock Forged Body for high strength and fully safety.
- Bonnet lock prevents accidents disassembly.
- Stem threads rolled and hard plated provides maximum service life.
- Two Part Stem tip stellated and hardened provides excellent flow control and ensures bubble-tight shut off.
- Ball Tip design: Which forms a bearing joint with the stem eliminates rotation between plug & seat at closure. This prevents scoring and galling up the valve seat and ensures long life in repetitive shut off service.
- Packing below stem threads prevents stem lubrication washout and isolates threads from system fluids.
- Hard seats are designed to reduce packing friction giving very low torque operation.
