Plunger Valve

Product Details:

• Face-to-face length: acc. to EN 558, basic series 15 - from DN 500 1.5 x DN
• With flange ends on both sides acc. to EN 1092-2
• Control valve in straightway type
• With customized control device depending on operating conditions
• Low actuating torque due to pressure balanced valve piston
• Rotationally symmetrical flow guidance

• Regulation is effected by own-medium controlled operation; the pressure difference of the medium generates the torque necessary for operation (the pressure difference must be at least 2 bar)
• Independent of the inlet pressure / flow fluctuations the valve regulates a higher inlet pressure down to a constant, lower outlet pressure
• Weight lever with double bearing, prevents the transmission of drop-weight forces to the valve bearing
• Drop weights in modular design for customised adaptation to operating conditions
