Shut Off Valves

Shut Off Valves

“SUPER” Shut off valves are designed specifically for use in industrial ammonia and large commercial halocarbon refrigeration systems. These rugged valves are a strong reliable component for modern industrial refrigeration applications and are suitable for liquid , suction, hot gas, discharge, recirculating liquid or 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 and withstand a high system pulsation and vibration, which can be present specifically in the discharge line.

Features and Benefits

“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: -60oF to +240oF ( -51oC to +116oC)

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 are manufactured on CNC machines

High tensile bolts, used to tighten the 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 of the packaging gland ensures perfect tightness in the whole temperature range

Packing glands are equipped with a scraper ring to prevent penetration of dirt and ice into the packing gland

Re-tighten gland nut in case of external leak
