Solenoid Valves

Solenoid Valves For Ammonia

Type SA Series Type SA5 solenoid valve is the direct acting type & type SA 17, SA 32, SA 42, SA 50 are higher capacity pilot operated solenoid valves for refrigeration & air conditioning applications.
Specifications :
1) Refrigerants : R717 (NH3), R22, R134A, R12, R502 etc.
2) Temperature of medium -40 to +80 C
3) Single coil (type KC -3) for all SA series valves.

Liquid Line Strainers

Strainer type TA with interchangeable filter insert is used in lines carrying fluorinated refrigerants, ammonia, water, brine, oil and gas which are Carefully designed to give favorable flow conditions. The design makes the filter easy to install and quick to inspect and clean. TA strainers are used in front of automatic control, pumps, compressors etc. for initial plant start-up where permanent filtration of the refrigerant is required. The filter reduces the risk of undesirable system breakdown as well as wear and tear of plant components.

FEATURES:
• Applicable to all common nonflammable refrigerants including R 717 and non corrosive gases/ liquids dependent on scaling material compatibility.
• Pleated filter net of stainless steel with a very large net surface ensures long intervals between cleaning and low-pressure loss.
• Retains contaminants, e.g. slag, and weld beads and swart.
• Pressure drop insignificant.

Gas Operated Solenoid Valves Type SPML & SPMLX

Gas operated Solenoid valve type SPML SPML valves are servo-operated main valves with screwed-on pilot solenoid valves. SPML valves use an external pressure source for opening (which means that no differential pressure across the SPML valve is required). This makes the valve especially suitable for low-pressure suction lines). The valves can be used in all types of refrigeration systems: Direct expansion, Pump recirculation, Natural circulation, Within their specified pressure and temperature ranges SPML valves can be used for fluorinated refrigerants (R 22, R 134a, R 404A, R 12, R 502, etc.) or ammonia (R 717). Especially suitable for systems where low pressure drop is required SPML remains open even though the pressure drop across the valve is 0 bar. SPML pilot-operated solenoid valves can be installed in: Suction lines, Return lines (liquid/vapour), Pressure-equalising lines, Bypass lines. Gas operated Solenoid valve type SPMLX two-step on/off SPMLX are 2-step servo-controlled main valves with screwed-on pilot solenoid valves. SPMLX valves use an external pressure source for opening (which means that no differential pressure across the SPMLX valve is required). SPMLX are used in suction lines for the opening against high differential pressure, e.g. after hot gas defrost in large industrial refrigeration systems with ammonia or fluorinated refrigerants. SPMLX opens in two steps: Step one opens to approx. 10% of the capacity, when the pilot solenoid valves are activated. Step two opens automatically after the pressure differential across the valve reaches approximately 1.5 bar. Replaces SPML with bypass solenoid valve, 2 signals and one timer. Stabilizes working conditions and eliminates pressure pulsations during opening after defrosting Provides safety against pressure "shocks" as the valve can only open fully when p < 1.5 bar
