Product Description
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 ApplicationsMHPSV-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 OptionsWith 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 ConstructionBuilt 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.
FAQs of MHPSV-SS High Pressure Stop Valves:
Q: How does the MHPSV-SS High Pressure Stop Valve ensure leak-proof performance?
A: The valve employs a precision-machined seat (PTFE or metal) combined with PTFE Chevron packing, providing an exceptionally tight seal and bubble-tight shut-off even under pressures up to 6000 PSI.
Q: What installation options are available for this stop valve?
A: MHPSV-SS valves can be installed with screwed (BSP/NPT), socket weld, or flanged end connections, and support both inline and flanged installation types, allowing for horizontal or vertical mounting based on system requirements.
Q: When is it recommended to use a stainless steel (SS316/SS304) stop valve?
A: These valves are ideal in environments where corrosion resistance, high strength, and long service life are critical, such as in hydraulic systems, pneumatic lines, and gas or oil processing industries.
Q: Where can MHPSV-SS valves be effectively utilized?
A: These valves are suited for industrial plants, gas distribution systems, hydraulic and pneumatic lines, and anywhere precise manual shut-off and leak-proof integrity are required.
Q: What is the process for maintaining these high pressure stop valves?
A: Routine inspection for wear, cleaning the surface finish, and checking the integrity of the PTFE/metal seat and packing are essential. The robust construction minimizes maintenance frequency while ensuring reliable operation.
Q: How does the non-rising stem design benefit the valves operation?
A: The non-rising stem allows installation in confined spaces without increasing the overall height during valve actuation, ensuring smooth operation and easier integration into various piping systems.
Q: What are the key advantages of choosing the MHPSV-SS stop valves?
A: These valves offer high precision, rugged durability, strong corrosion resistance, bubble-tight shut-off, and flexible mounting and connection optionsideal for demanding industrial and process control applications.
