Instruments Valves

Condensing and seal pots

barilotto condensa

The integral type pots are made from seamless pipe according to ANSI B36.10. The connection bushing are assembled to the body employing the best welding techniques in order to obtain the maximum resistance to pressure and temperature.

Our operators are all skilled welders passed throught qualifications tests of the ASME IX. All pots are hydrostatically tested at 1,5 the nominal pressure.

Different materials are used for manufacturing seal pots and condensing chambers in order to suit all applications and the conditions of pressure temperature and corrosion involved.

Usually pots are manufactured in stainless steel material, carbon steel and on demand all the other kind of materials (Monel 400, P11, P22, etc.)

 

Seal pot with vent valves

barilotto spurgo

Ideal for low-rate volume at full load. Supplied with antitamper trim, mounting holes compression fittings as standard.

This kind of pots are made from bar in 316/316L stainless steel material and on request they are also available in Monel 400, Hastelloy C, etc.

 

 

Sampling cylinders

cilindro campionamento

VIMEC sampling cylinders are designed and manufactured to provide long performance life and maximum safety to the user for the safe containment and trasportation of samples of gases and liquids.

The cylinders are available in different capacities and cylinders ends come in 1/4" NPT-F and 1/2" NPT-F connections.

They are available in 316 and 316L stainless steel material on request are available also Monel 400, carbon steel material, etc.

 

 

Instrument double block and bleed valves

valvola doppio intercetto

Double block and bleed systems represent a new solution for instruments hook-up with the following advantages:

  • Reduction in possible leakage points
  • Saving of weights and overall dimensions until to 70%
  • Shorter times in assembly
  • Simplifed purchase and store management

This modular systems found an ideal application both in sampling and injection systems.
Double block and bleed are available in different type of materials (316L, Monel, Duplex, Hastelloy,...) and connections (threaded/threaded, flanged/threaded).

 

Bar-stock pressure gauge valves

valvola portamanometro

The pressure gauge valves are pratical low cost valves for the installation of pressure gauges and pressure switch.

These valves provide for cut-off and zeroing of instruments, thanks to a rear needle valve which clears a vent hole placed on the side of the body.

Different models are available with a large combination of connections and pressure rating. Lighter series is also available; it is optimal in air instruments circuits.

Assembled with air distribution pots or usually for low pressure, different models of valves with more outlets complete the range of needle valves. Available in different diameter from 1/8" to 1" and in every kind of materials required.

*For valve during the welding operation: SW, it is necessary to cool adequately the valve body, in order to avoid any deformation to the gaskets.

 

 

Limit switch box

Ball valve Microswitch box

  • Indicator: Visual position indicator.
  • "Quick set" cam: The sitting of the cams is a micrometical one, and it’s obtained by spIine
  • connection. The position of the cams is ensured thanks to a spring, which acts preventing any casual mouvement. The regulation is performed without any tool.
  • Multipoint terminal strip:Terminal strip number with 9 contacts is standard for micro switch. There are connected solenoid valve service.
  • Dual wire potting:The Box has two conduit entries thread PG13,5.
  • Cover: The cover is correctly positioned on the box thanks to two centering points. The fastening screws are kept in their seat, so as not to get lost once the box is open.
  • Electric card: The electric cards have been studied in a way that they aIl can be interchangeable and easily replaceable without demounting the stem.
  • Bracket: The bracket has been conceived for an immediate assembling on the pneumatic actuators, in accordance with the regulations VDl / VDE 3845 NAMUR.

Globe Valves

sbc globe valve

A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.

Gate Valves

gate2

The gate valve opens by lifting a round or rectangular gate/wedge out of the path of the fluid

The main feature is the sealing surfaces between the gate and seats are planar, so gate valves usually are used when a straight-line flow of fluid and minimum restric­tion is desired.

 

The gate faces can form a wedge shape or they can be parallel.

 

Gate valves list:

 

  • Gate valves series ANSI 2500
  • Gate valves series ANSI 1500
  • Gate valves series ANSI 900
  • Gate valves series ANSI 600
  • Gate valves series ANSI 300
  • Gate valves series ANSI 150

Hydraulic actuators

attuatore idraulico

A cylinder or fluid motor that converts hydraulic power into useful mechanical work

 

The mechanical motion produced may be linear, rotary, or oscillatory.

 

Operation exhibits high force capability, high power per unit weight and volume, good mechanical stiffness, and high dynamic response.

 

These features lead to wide use in precision control systems and in heavy-duty machine tool, mobile, marine, and aerospace applications.

Pneumatic Actuators

attuatori rotanti

PRINCIPLE OF OPERATION

Counter clockwise output operation is achieved by inserting pressure into Port 'A', to force the pistons apart thus rotating the actuator pinion counter clockwise.

 

During this operation, air from the outer chambers is exhausted through Port 'B'. Clockwise output operation is achieved by reverse of the above and inserting pressure into Port 'B'.
