The new type of shut-off valve –STC is an exclusive range of valves which is manufactured in the state-of-the-art Danfoss India factory located at Oragadam and caters to the needs of different industrial refrigeration plants.
The new shut-off valves are designed in accordance to European standards to meet with the challenges in industrial refrigeration application requirements in India. New enhanced product design features include new packing gland, gasket and a Teflon cone which will enable higher plant safety, lower maintenance and longer life span. The new packing gland ensures a unique, tight and secure seal throughout the operating conditions within specifications, whereas the Teflon cone ensures a perfect rigidity in the range.
Along with growing demand for industrial refrigeration products in the Indian market, there is a need to enhance the automation and safety of plants through reliable and efficient products. Designed to work in harsh and humid environments, the new Danfoss valves provide reliable operation in various industrial refrigeration plants.
Here are some of the key features of the new STC shut-off valve:
The STC comes in angleway and straightway versions and ranges from DN 15-150 with cap or hand wheel options. The valves ensure favorable flow characteristics and are easy to dismantle and repair if required. The new packing gland design is implemented across the whole range. It is an improvised version of the proven high strength design and customers are sure to get benefits from enhanced safety and long lifetime. The aluminum gaskets added to the DN 15-40 act as a primary sealing and ensure that the O-ring seal does not come in direct contact with the refrigerant, which is used as a backup to enhance the sealing performance. Non asbestos flat gaskets are introduced for sizes DN 50-150. This is the same as for high strength valves which increases the contact area and improves the effectiveness of the sealing. The Teflon for the cone is made up of 25% carbon filled Teflon to assure long lifetime through high resistance to wear and tear. All valves are 100% tested in regards to leakage and strength. All valves are manufactured in the state-of-the-art factory in India with high quality consciousness and focused continual improvement in compliance with the best in industry standard TS16949.
The SVA shut-off valves in stainless steel are available with DIN connections in angleway and straigtway versions and with standard neck (SVA-S SS). The valves are designed to meet all industrial refrigeration application requirements and are designed to give favourable flow characteristics.
The stainless steel valves REG-SA SS and REG-SB SS are angleway and straightway hand-operated regulating valves, which act as normal shut-off valves in closed position. REG-SA SS with the A cone is designed for expansion lines. REG-SB SS with a B cone is designed for regulating purposes e.g. liquid lines.
SCA-X SS are check and stop valves in stainless steel with a built-in stop valve function. SCA-X SS are available in angleway versions. The valves are designed to open at very low differential pressures, allow favourable flow conditions and are easy to disassemble for inspection and service.
CHV-X SS stainless steel check valves are available in angleway versions. The valves are designed to open at very low differential pressures, allow favourable flow conditions and are easy to disassemble for inspection and service. The valve cone has a built-in flexibility to ensure a precise and tight closing.
FIA SS are a range of stainless steel angleway and straightway strainers, which are carefully designed to give favourable flow conditions. The design makes the strainer easy to install, and ensures quick strainer inspection and cleaning.
Valves for use in environments where optimum protection of external surfaces on valves and fittings is important, e.g. for outdoor applications, in corrosive atmospheres and for food applications. Applicable to HCFC, HFC, R717 and R744.
Refrigerants: HCFC, non flammable HFC, R717 (Ammonia) and R744 (CO2). Max. operating pressure: 52 bar g (754 psig). Valves for higher operating pressure available on request. Full temperature range: –60 - +150°C (–76 - +302°F).
EVRS and EVRST are valves made of stainless steel.EVRS 3 is direct operated, EVRS 10, 15 and 20 are servo operated, EVRST 10,15 and 20 are forced servo operated valves.EVRS and EVRST are used in liquid, suction, hot gas and oil return lines with ammonia or fluorinated refrigerants.
