SUPER 1968 shut off valves are designed specifically for use in industrial ammonia and large commercial halocarbon refrigeration systems. These rugged valves are a reliable component for modern industrial refrigeration applications and suitable for liquid, suction, hot gas, discharge, recirculating liquid and oil lines. These are designed to give favourable flow characteristics and, are easy to dismantle and repair when necessary. The valves are designed to ensure perfect closing to withstand a high system pulsation and vibration, which can be present specifically in the discharge line.
SUPER 1968 shut off valves are available in angle way and straight way versions
Internal PTFE back seating design to replace seal while the valve is still operating
Non asbestos gaskets
Safe working pressure 400 psig (27 bar)
Temperature range: -60℃ F to +240℃ F ( -51 C to +116 C)
The valve is design to withstand high internal pressure. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion,
Extended neck provides greater insulation clearance
Individual pressure testing of each valve
All components on CNC machines
High tensile bolts to tighten bonnet, give extra life to the valves
All valves are painted with premium quality paint that protects valves in all weather conditions
Suitable for R717 (Ammonia) ,R744(CO2) HCFC & HFC, chemical and petrochemical applications.
The temperature range packaging gland ensures perfect tightness in the whole temperature range
Re-tighten gland nut in case of external leak
