Noise Reduction Measures

• Based on Union’s characteristics and ISA calculation formula, noise prediction is performed, and suitable countermeasures are proposed to the customers.
  Installation of a Union multi-plate.
  By installing the Union multi-plate, noise can be reduced by about 10 dBA.
  *For details, please consult with us and check the specifications.

Cavitation Countermeasures

• Based on Union’s characteristics and ISA calculation formula, cavitation prediction is performed, and suitable countermeasures are proposed to the customers.
  Valve flow direction optimized processing.
  Installation of a Union multi-plate.
  *For details, please consult with us and check the specifications.

Environmental Protection Gland

A double-seal structure completely seals any leakage from the valve gland.

• TA-LUFT Standard:
  TA-LUFT is a structure designed to prevent leaks from the valve gland for the purpose of environmental protection.

Structure Feature

Positioner

The positioner is used to adjust the valve opening degree as desired by receiving either an electric current signal (electro-pneumatic positioner) or an air pressure signal (pneumatic positioner) from the control room.
Union + Unipower + Positioner
This combination provides excellent controllability.

Electro-Pneumatic

Pneumatic

Features

• Rotary type: Equipped with a linked lever type that allows for easy zero adjustment and range adjustment.
• Vibration resistance: No resonance in the range of 5-200 Hz (2G).
• Linearity: ±1% (single operation), ±2% (compound operation).
• Hysteresis: 1% (single operation), 1% (compound operation).
• Can be adapted to all installation positions.
