MGLG are Manik Glass level gauges made from special low temperature steel plates that are designed to

meet the requirements of modern industrial refrigeration. They are supplied with stop valves for connection and

isolation to the refrigeration system. The MGLG provides an accurate easy reading of the refrigerant level inside

the pressure vessel over which they are mounted. The top and the base frame are mounted together with the

help of SS Allen bolts. This makes it easy for insulation, inspection and service onsite, if required.

All gauges are supplied with a built-in safety system (non-return device) and in case a glass gets damaged,

the safety system due to the pressure of the refrigerant, shall prevent refrigerant loss to an absolute minimum.

Manik Engineers LIQUID EYE gives simple indication of actual liquid levels in industrial and commercialrefrigeration systems. When liquid refrigerant is present the distinctive reflex glass appears dark; when vaporrefrigerant is present, the glass is light. The long neck housing provides enough length for ease of welding andinsulation clearance for low temperature applications. The optional frost-free shield facilitates clear viewing ofrefrigerant level under frosting conditions.The Liquid Eye is available in 2 types :1. MLE - Which can be directly welded upon pressure vessels or liquid columns2. DMLE - Which has dual glass for viewing the internal media and is mounted inline.

For installations in seaside areas and outdoor applications where the air is highly humid and corrosive, Stainless

Steel Valves are recommended which provide elevated surface protection against corrosion. These valves

are also recommended in applications where regular surface treatment is carried out to prevent fungal and

bacterial growth.

The Manik MHPSV-SS Valves have been specially design for such applications.

The MHPSV-SS Stop Valves are refrigerant shut-off valves designed to be socket-welded or butt-welded directly

to steel piping, thereby eliminating potential leaky flanges or threaded joints and simplifying installation. These

valves fit all requirements of the latest refrigeration technology and have desired flow characteristics with a low

pressure drop design. The MHPSV-SS has specialised internal back- seating support which allows the shaft

seal (packing gland) to be replaced while the valve is still under working condition. Interchangeable handwheel

or seal cap available. These valves are available in angle and globe types. The Teflon seat lends durability to

the seating surface.

Optimal Performance in High Pressure Applications

MHPSV-SS stop valves are specifically crafted for high-pressure environments, supporting pressures up to 6000 PSI. Their robust SS316/SS304 build and advanced sealing technology deliver exceptional leak-proof operation even under extreme conditions, making them ideal for industrial, gas, hydraulic, and process lines.


Versatile Installation and Connection Options

With compatibility across BSP, NPT, Socket Weld, and Flanged connections, these valves suit a wide variety of system configurations. Their flexible installation design supports both horizontal and vertical mounting, providing seamless integration into new or existing setups.


Durable, Corrosion-Resistant Construction

Built from high-grade stainless steel with polished or shot-blasted finishes, MHPSV-SS valves resist corrosion in harsh working environments. The precision-machined body, PTFE/metal seat, and PTFE Chevron packing further enhance valve longevity and reliability in demanding applications.

With repeatability and a wide range of flow settings, this Flow Switch Type FS-100 E provides precise flow sensing. Its robust design provides long-life dependability in both water and oil. It is perfect for finding incorrect flow rates in systems that handle a lot of volume for lubrication, cooling, or process. The Flow Switch Type FS-100 E improves exterior versatility while retaining the same level of precision and durability as switches with fixed settings. Your selection of flow settings is wide with this adaptable switche within a certain range.

Durable Construction and Compatibility

Built with a sturdy brass body, the FS-100 E Flow Switch withstands challenging industrial conditions. It is suitable for use with hot or cold water and various oils, ensuring reliable flow monitoring without corrosion or wear. The device integrates seamlessly into pipelines using its BSP threaded connections and PG9 cable entry.


Versatile Applications for Enhanced Protection

Designed for system safety, the FS-100 E is widely used in HVAC, pump protection, fire suppression, and water treatment. Its mechanical paddle mechanism and SPDT output facilitate prompt response to flow status changes, helping prevent equipment damage and supporting process control across diverse industries.
