J1521G / J1521M

Arion Strainer

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.

  • Maximum working temperature:
    • Glass: 104° F / 40° C
    • Metal: 208° F / 80° C
  • Maximum working pressure: Glass and Metal: 232 psi / 16 bar

J0098A / J0097A

Strainers

There are two versions of the standard AISI 316 stainless steel strainer with 40 mesh stainless steel screens.

The standard strainer J0098A has a 3/8 in / 9.5 mm blowdown/maintenance port for access to the screen and the 3/8 in / 10 mm NPT inlet and outlet connections. The J0097A strainer provides a standard 1/4 in / 6.35 mm sensing / gauge connection. All stainless steel construction is available as an option.

The strainer shall be a Singer Model J0098A or J0097A (additional 1/4 in / 6.35 mm connection).

  • The strainer body shall be of 316 stainless steel construction.
  • The strainer shall be mounted externally on the main valve for easy access and internal screen shall be easily removed and cleaned.
  • The strainer shall have the outlet located ninety degrees to the inlet.
  • The body shall have a 3/8 in / 10 mm NPT plug for easy access and / or installation of an optional ball valve for easy screen flushing.
  • The Model J0097A shall be complete with an additional unfiltered 1/4 in / 6.35 mm NPT sensing or gauge connection.
  • Maximum working temperature: 180° F / 82° C
  • Maximum working pressure: 400 psi / 27.6 bar

Model 10 & 12

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.

Standard Materials:
- Body: ASTM B16 brass Seat Ring: ASTM B-16 brass
- Inner Valve: Lexan Seals: Buna-N

  • Maximum working temperature: 180° F / 82° C
  • Maximum working pressure: 400 psi / 27.6 bar

J0053A

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.

Standard Materials
- Forged brass body Urethane disc
- Stainless steel stem Stainless Retaining Ring Buna-N seals

  • Maximum fluid temperature: 140° F / 60° C
  • Maximum pressure rating: 2000 psi / 138 bar

J0074A

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.

Standard Materials
- Forged brass body, Buna-N seals and stainless steel stem

  • Maximum fluid temperature: 180° F / 82° C
  • Maximum pressure rating: 2000 psi / 138 bar

852-B

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.

  • Maximum operating temperature: 180° F / 82° C
  • Maximum working pressure: 400 psi / 27.6 bar

Fixed Restriction

Fixed Restriction

  • ‘A’ 1 / 8 in / 3.2 mm orifice
  • ‘B’ 1 / 16 in / 1.6 mm orifice
  • ‘C’ 3 / 32 in / 2.4 mm orifice
  • ‘D’ 1 / 4 in / 6.35 mm orifice
  • ‘E’ 7 / 64 in / 2.8 mm orifice

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.

  • Maximum working temperature: 180° F / 82° C
  • Maximum working pressure: 600 psi / 41.4 bar
  • Connections: 1/4 in (no metric equivalent) NPT

Model 26

Flow Stablizer

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.

  • The flow stabilizer body shall be of stainless steel construction.
  • The flow stabilizer shall allow unrestricted flow into the main valve bonnet while offering adjustable restricted flow out of the bonnet.
  • The flow stabilizer shall be self cleaning and resistant to plugging
  • The Singer proprietary tapered internal orifice and inner valve shall offer precise adjustment, which shall be lockable by utilizing the top locknut.
  • The flow stabilizer shall improve low flow stability when incorporated with other “Singer Low Flow” proprietary automatic control valve enhancements
  • Maximum Working Temperature: 180° F / 82° C
  • Maximum Working Pressure: 400 psi / 27.6 bar
  • Connections: 1/4 in (no metric equivalent) NPT
