Refrigeration controls

Solenoid valves (MS7A, MS8A, SA, MSVA)

Spring-closing, Teflon-seated valves for ammonia, CO₂ and freons, with matching CAS strainers (15–32 mm).

MS8A / MS7A

½ in, ¾–1¼ in, ductile iron

SA series

15–50 mm

MSVA

15–40 mm

MOPD

21 bar (300 psi)

Servo-operated solenoid valves (SPML, SPMLX)

Pilot-operated main valves for suction, return and bypass lines. SPMLX opens in two steps for suction lines after hot-gas defrost.

Sizes

32–125 mm

Liquid level controllers and switches (PVR-V2, LC 101, CLLS-100)

Control liquid level in accumulators and separators, or drive an alarm or pump. Flameproof versions available.

Differential

10–40 mm

Float housing

19 bar, IP 65

Float switches (FKS 39)

Electro-mechanical float switch for level control or low/high alarm. Switch box replaceable without opening the system.

Reflex glass level gauges (RGLLI, MGLG, PVR-LL1)

Frost-free reflex gauges with toughened borosilicate glass; balls in the valves stop flow if a glass breaks.

Lengths

12–60 in

Pressure

up to 40 bar

Pressure gauges and cut-outs

SS 304 glycerine-filled ammonia gauges, differential pressure cut-out switches and compressor gauge boards.

Temperature, humidity and pressure instruments

Digital temperature and humidity indicators and controllers, pressure indicators, temperature sensors with thermowells, temperature-humidity transmitters and pressure transmitters.

Solenoid and float coils

Replacement coils for solenoid valves and float switches.
