SINTESI brass regulation ball valve

Product catalog summary

Overview
The document is a datasheet for the SC3.1-21 regulating ball valves by Comparato Nello SRL, a company certified under UNI EN ISO 9001:2015. These valves are used in various systems such as zone heating/cooling, HVAC, alternative energy systems, and household automation.

Key Features

Fast push connection with actuator
Equal-percentage characteristic curve with adjustment disc
Selectable Kvs values
Sealing closure
Available in 2-way and 3-way configurations from 1/2"-DN15 to 2"-DN50

Technical Specifications

Fluid type: Water (max 30% glycol)
Fluid temperature: +5°C to +100°C
Nominal pressure: 16 bar
Δp max: 3.4 bar
Characteristic curve: Equal-percentage
Operating angle: 90°
Leakage class: EN60534-4

Materials

Body, coupling, ball, and rod: Brass CW 617N
Seals: PTFE with 15% graphite
O-rings: EPDM
Stop ring: Steel
Modulator: PPA (AMODEL 1145 HS) and PA 6.6

Flow Direction and Installation
The valves are designed for use with 3-point or proportional actuators, providing a motorized ball valve with an equal-percentage regulating curve. The adjustment disc compensates for non-linearity, enhancing system stability. The 2-way valve must be installed according to the flow direction indicated by an arrow.

Dimensions
The document provides detailed dimensions for both 2-way and 3-way valves, specifying sizes for DN15 to DN50 models.

Control Options

3-point modulating control
Proportional modulating control
Remote control
