Valves for cryogenics

Valves for cryogenics

Product catalog summary
Overview: This document is a technical guide for selecting solenoid valves specifically designed for cryogenic applications. It covers various series of valves, their specifications, features, and operational guidelines.
Specifications: The guide details solenoid valves available in sizes ranging from 1/8" to 2". It includes both Normally Closed (NC) and Normally Open (NO) configurations. The valves are engineered to handle cryogenic media down to -196°C and are available with brass or stainless steel bodies.
Electrical Characteristics: The valves operate on various AC and DC voltages with a tolerance of ±10%. They have a 100% duty cycle and are protected under IP65 standards. The standard electrical connection is a PG9 Din Connector.
Flow Data: The document provides flow data for different valve sizes, indicating the Kv value, which represents the flow rate of water at a 1 bar pressure drop. The valves are designed for high flow rates with large porting.
Features & Benefits: Key features include PTFE seals, high pressure capabilities, and options for stainless steel bodies. The valves are degreased and individually packaged for cryogenic service, ensuring reliability and safety.
Dimensions: Detailed dimensions are provided for each valve size, including options for mounting brackets and LED power indicators.
ACAST Series: This series features an angled body for higher flow rates and an anti-water hammer design. It offers both single and double acting options with a compact design and maintenance-free operation.
ACPNX Series: These are Normally Open valves with heavy-duty design and wide temperature range capabilities. They are suitable for applications requiring quick response times.
Usage Instructions: The guide includes instructions on how to use flow charts to select the appropriate valve based on flow requirements and pressure drop.
Compliance: All valves are tested in accordance with BS EN 12266-1 and are PED compliant, ensuring they meet industry standards for safety and performance.
