Who is Sirca International and what does it make?

Sirca International is an Italian manufacturer from Trezzano Rosa, near Milan, of butterfly valves, ball valves, pneumatic actuators and control accessories, supplied separately or as complete valve–actuator assemblies. The company started in the late '70s with pneumatic automation and control systems, and the quarter-turn rotary pneumatic actuator has remained its core product. For a quotation, send us the series (for example 301, 401N, 501M, S30 or AP), the nominal diameter, the pressure class and the fluid.

The butterfly valves cover three levels of demand. The 301 series has a resilient seat, DN40–DN1000, Wafer, Lug or double-flanged versions, working pressure of up to 20 bar and NBR, EPDM or Viton liners reinforced with a metal ring; the 301TSS variants with a PTFE (polytetrafluoroethylene) seat and 301TT PTFE-lined work on chemical fluids. The 401N series, with double eccentricity, DN80–DN1400, ASME Class 150, between −40 and +220 °C, has a PTFE seat with carbon-graphite and, on request, metal-to-metal sealing in Inconel 625. The 501M series, with triple eccentricity and a metal seat of weld-deposited Stellite, reaches DN1400, Class 600 or PN160 and temperatures between −196 and +815 °C, for high pressure, high temperature, critical service and cryogenic duty.

The ball valves include the S10 Wafer series with flat body and full bore, DN15–DN200, up to 40 bar, the S30 series with split body, up to 100 bar and Class 600, the S30T double-shaft (trunnion) valve, two-piece or three-piece versions and S70 and S80 three-way valves. The AP and APM actuators, with rack and pinion, double-acting or spring-return, come in sizes AP0–AP12 and torques of 2.4–7,500 Nm, with an ISO 5211 flange and NAMUR interface; the range also includes the APG scotch-yoke pneumatic actuator. The range is completed by manual gearboxes, handles, MBX limit switch boxes and SVS solenoid valves. Depending on the series, the valves carry PED (Pressure Equipment Directive), ATEX, SIL (safety integrity level) and API 607 fire safe certifications.

The range also includes the APG scotch-yoke series.

Why Sirca International?

Three butterfly valve designs — 301 resilient, 401N double eccentric and 501M triple eccentric with metal seat
Wide temperature range for the 501M — from −196 to +815 °C, with a weld-deposited Stellite seat
Valve–actuator assemblies from the same source — AP/APM and APG actuators mounted and set on Sirca valves
Standard ISO 5211 and NAMUR interfaces — the AP actuator can also be mounted on existing quarter-turn valves
Certifications by series: PED, ATEX, SIL and API 607 fire safe — the documents required by process plants

How do we supply Sirca International in Romania?

We can quote Sirca butterfly valves from the 301, 401N and 501M series, S10, S30 and S60 ball valves, AP, APM and APG pneumatic actuators, manual gearboxes and MBX and SVS accessories, separately or as a mounted assembly. For a correct quotation, send us the series from the nameplate, the nominal diameter, the version (Wafer, Lug, flanges), the pressure class, the body and seat materials, the fluid and the temperature, and for assemblies the control air pressure and the type of action. We supply the items made to order, through EU supply channels, usually in 1–4 weeks; an actuator can ship in 24–72 h when the item is available locally or at the supplier.

We quote Sirca valves and actuators as parts or as ready-set assemblies, while installation on the pipeline remains with your execution team.

Frequently asked questions about Sirca International

What does Sirca International produce?

Sirca International produces, at Trezzano Rosa near Milan, resilient-seated, double eccentric and triple eccentric butterfly valves, two-piece or three-piece, split-body or three-way ball valves, rack-and-pinion and scotch-yoke pneumatic actuators and control accessories, also supplied as automated assemblies.

How do I choose between the 301, 401N and 501M butterfly valves?

The 301 series, with a resilient liner, is chosen for water and industrial fluids up to 20 bar and +160 °C. The 401N series, double eccentric with a PTFE seat, works on aggressive fluids up to +220 °C, and the 501M, with metal sealing, for high pressures, temperatures up to +815 °C or cryogenic service.

Do you supply Sirca valves in Romania and how fast?

Yes. We bring in Sirca valves and actuators to order, through EU channels, usually in 1–4 weeks. A 301 butterfly valve or an AP actuator can ship in 24–72 h when the item is available locally or at the supplier. For 501M valves of large diameters or in high ASME classes, depending on the brand and specifications, the lead time may be longer.

Can you fit a Sirca actuator on an existing valve?

Yes, if we know the ISO 5211 flange, the shape and size of the shaft and the operating torque of the valve. On these data we choose the AP or APM actuator size, double-acting or spring-return, and the coupling. For an existing Sirca valve, the series and diameter from the nameplate help us.

What do I send for a quotation on a Sirca assembly?

The valve series, nominal diameter, Wafer, Lug or flanged version, pressure class, materials of the body, disc and seat, the fluid and the temperature. For the actuator: double-acting or spring-return, air pressure, fail-safe position, the voltage of the SVS solenoid valve and whether you want an MBX limit switch box.

How do I request a Sirca International quotation?

Send the Sirca International code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
