They are a cartridge type, which allows easy installation.■ SpecificationsModelProduct nameCheck valveKCHKT5KT7KT9■KCHOrifice■Characteristics of pressure loss (KCH)cat-No.78E since2017■ References for selecting an orifice (KT5/7/9) for pressure reductionHole diameterCracking pressuremm0.1 MPaD10-500: push side + high-pressure hoseD30-850: push side + high-pressure hoseMeasurement conditions Hydraulic oil: 40cSt 35 °CNote:The amount of compression of the cylinder capacity is calculated based on 4 % of the push-side capacity at 70 MPa.Specifications■KT9Amount of compression0.293 + 0.05 = 0.3431.475 + 0.05 = 1.525 cm3 ( x 1000)Blocks “T → P” flow for 2-way valves and “A → P” flow for 3-way valves.Used when a rapid flow control is required for a pressure reducingcircuit, accumulator, etc.Blocks flow that exceeds the rated capacity of the valve.■KT7■Characteristics of pressure loss (KT5/KT7/KT9)Internal volume cm3 ( x 1000)7.328 + 0.23= 7.55836.867 + 0.23= 37.097123
