Filters #51060

valves and filters form an essential part of any process plant or system in a wide range of applications from relatively simple on/off functions to flow control, pressure relief and filtering.

all wetted parts of valves and fitters described in this section of the catalogue are constructed from borosilicate glass, ptfe, ceramic, fep, pfa or tantalum thus ensuring maximum resistance to corrosion. In addition, as valves have a glass body, visual monitoring of the valve operation is possible at all times.

for standard flat buttress end connections from dn 25 to dn 150, it is possible to achieve a 3deflection in the joint by using a flexible gasket. Details of these and all other couplings and gasket can be found in section -couplings.

the valves described in this section of the catalogue comply, which means that 90bends, tee pieces and equal crosses(see section pipeline components)are interchangeable with certain type such as angle valve.

dn refers to the nominal bore. Unless otherwise stated, all dimensions are given in mm.

for permissible operating conditions, unless otherwise stated in the individual description, please see section technical information.generally, the maximum operating temperature for valves is 200c but temperature above ambient, particularly in the range from 120c to 200c, impose restrictions on the permissible operating pressure.

a wide variety of valves are available for a range of purposes. All have borosilicate glass bodies. As a result operation of the valve can be checked visually. In practically every case glass is combined with ptfe, which ensures that the valves have maximum resistance to corrosion.

all the valves are suitable for use under full vacuum. Pressure ratings at ambient temperature are indicated in the tables applicable to each type of valve.

the maximum operating temperature is 200 c but temperatures above ambient particularly in the range 120 c to 200 c, impose restrictions on the permissible operating pressure. In case of doubt it is advisable to consult us.

these valves comply with iso 3587 where applicable. Thus maximum interchangeability of compatible components is assured. For example, angle valves can be interchanged with 90 ells, equal tee pieces and equal crosses.

dn refers to nominal bore. Unless otherwise stated dimensions are in millimeters. Figures given for maximum recommended working pressure represent pressure above atmospheric.

agitated glass nutsche filter

agitated glass nutsche filteris a closed vessel designed to separate solid and liquid by filtration under vacuum. The closed system ensures odourless contamination free and non-polluting working conditions maintaining product purity and hygiene. Agitated nutsche filters are extensively used in herbal products, chemical product development, kilo lab operation, pharmaceutical manufacturing, agro chemical and the food industry.

general description

a typical unit consists of a dish shape vessel vessel with a perforated plate. The entire vessel can be kept at the desired temperature by using a jacketed and stirrer (blade and shaft) through which heat transfer media can flow. The vessel can be made completely leak-proof for vacuum or pressure service. The base plate is having arrangement of bolting bar to hold the filter cloth. Suitable nozzles can be provided including manhole and side discharge nozzle. Ptfe lined stirrers are used for agitator shaft and solid ptfe blades are used to take high torque generation during solid discharge and re-slurring operation.

process steps of agitated nutsche filter with agitator and discharge valve are:-

1) filtration2) washing of filter cake3) repeat mix or washing of the cake4) convection drying of the cake5) smoothing with compression of the cake6) discharge of the wet or dried cake.

drive assembly consist of motor with vfd, mechanical seal is provided for vacuum application. Borosilicate glass vessel with different nozzles, manual/hydraulic system is provided for movement of agitator and discharge valve. Ptfe filter support plate.

advantages of glass nutsche filter

• vacuum filtration possible.
• glass being transparent, offers visibility of processes.
• inert gas atmosphere can be maintained.
• minimal contamination of the cake.
• very high solvent recovery.
• solvents are in closed systems, so no toxic vapors are let off in the atmosphere.
• personal safety is maintained and heat transfer surfaces can be provided to maintain filtration temperature.

garg offer glass anf from 10 l to 200 l for kilo lab operations with and without jacket , with and without stirrer. Our sales/technical team will be glad to assist you desinging the best suitable system for your process requirements.
