Limit Switch Indicator
The X129 limit switch is actuated by the opening and closing of a main valve. The assembly is fully adjustable over the entire valve stroke. Layout variations allow up to four separate switches to be mounted and actuated off the same stem.
Select Singer main valve specifications from the main valve section and incorporate the following addendum:
The Arion series strainers are more suited to dirty water applications. The dirt is trapped on the inside of the double mesh screens and collects in the bowl. The double port construction of the housing prevents the particles from re-entering the flow stream.
The collected dirt can be flushed directly out to drain by opening the blowdown. The J1521G strainer has a glass collection bowl, while the J1521M strainer has a metal bowl. Standard pressure rating for the strainer is 232 psi / 16 bar. Body connections are 1/2 in / 15 mm NPT and it comes complete with a 3/8 in / 9.5 mm blowdown valve and a discharge tube.
The strainer shall be a Singer Model J0098A or J0097A (additional 1/4 in / 6.35 mm connection).
Pilot Check Valves
The 10 pilot check valve is standard on all 106 and 206 series valves requiring a pilot check function such as BPC, PR-C, RPS-C types. It is designed to require a low “cracking” differential pressure to open. The 12 has a higher “cracking” pressure and requires more differential pressure to open.

Micrometer Flow Control Valve
Micrometer flow control valves allow for precise flow control. There is full flow in one direction and adjustable restricted flow in the opposite direction. They are standard on certain models, such as BPC pump control valves and available as an option for other applications. Standard end connections are female-to-female 1/4 in / 6.35 mm NPT.
- Forged brass body Urethane disc
- Stainless steel stem Stainless Retaining Ring Buna-N seals
Micrometer Needle Valve
Micrometer needle valves allow for precise speed control. There is virtually infinite flow adjustment in both directions. Standard end connections are female-to-female 1/4 in / 7.5 mm NPT.
- Forged brass body, Buna-N seals and stainless steel stem
Needle Valve Speed Control
The 852-B needle valve is a pilot speed control valve. The body is brass and the stem is stainless steel with a fine thread for controlling flow. O ring packing assures leak proof, trouble free service. 1/4 in / 7.5 mm NPT female to female end connections.
The fixed restriction is a 303 stainless steel bodied fitting with a stainless steel orifice plug. The fixed restriction controls the flow rate in the pilot system. The orifices are sized to provide the proper control to a select series of valve sizes only. This all stainless steel version replaces all previous versions of the brass body, with stainless steel insert.
The 26 flow stabilizer is a self-cleaning, opening speed control. It is used in conjunction with a fixed restriction orifice that is usually threaded into port 3. The 26 stabilizer allows free flow down to the bonnet (port 1) and restricts flow up from port 1.
The 26 stabilizer is used as the standard flow stabilizer (opening speed control) on model 106-PR or 206-PR pressure reducing valves or any other model that requires low flow stabilization.
The flow stabilizer shall be a Singer model 26.
All Singer valves are fitted with Copper tubing as standard. There are optional upgrades to Stainless Steel or Stainless Steel braided hose available.
