Working pressure up to:

Working temperature are as follows:

PTFE:-65°F to 450°F (-54°C to 232°C)

PEEK: -65°F to 450°F (-54°C to 232°C)

Actuate at quarter-turn.

Directional stem flats show open or closed position.

Bottom-loaded stem prevents stem blowout and enhances

system safety.

High-strength stem bearing provides smooth actuation and

eliminates galling between valve stem and body.

It may be required to adjust the packing during the service

life of the valve.

FITOK ball valves are designed to be operated in a fully open

or fully closed position.

FITOK process and Instrumentation products pipeline's pressure - temperature rating depends on flange end connection.

We offers a variety of sizes and pressure ratings of the flange in accordance with ASME B16.5 Specifications.

Below listed data adopts ASME B16.5-2003 Table 2-2.2 and Table F2-2.2. The rating data are based on stainless steel F316/F316L.

PTFE:-65°F to 450°F (-54°C to 232°C)

Graphite: -65°F to 1200°F (-54°C to 649°C)

Two-stem design: thread hardened upper stem and smooth

surface hardened lower stem.

Upper stem thread lubricant is isolated from system fluid.

The non-rotating lower stem's linear instead of helical movement

avoids galling damage to the seat and tip, avoids galling damage

to the seat and tip, as well as reduces the total friction area betw-

een the packing and the lower stem.

Stem back seating seals in fully open position.

Panel mounting is available as an option.

Double lock-pins enable steady and durable fastening of the

handle.

Bolted bonnet enhance strength and reliability.

Back seat design provides secondary stem sealing and prevents

stem blowout.

Adjustable gland flange allows easy access to the packing gland

and packing adjustment for an effective stem seal.

Investment case yoke is formed by precision casting which

enhances strength and perfect stem alignment.

Two handle pins make the handle fixed firmly and lastingly.

Injection Double Block & Bleed Valves

Injection of chemicals and other media into the process stream can be accomplished with this design. A check valve is installed

process fluid from reaching the inlet injection position. There is a 0.125" (3 mm) hole in the injection nozzle orifice.

The length of the injection nozzle orifice can be manufactured to meet customer requirements and needs to be specified.

The injection orifice can also be rotated. Injection valves can be provided in most of the styles and options offered for the DBB

ranges.

Function - injection

Injection Quill

The injection quill length (L) is manufactured to meet customer requirements.

The injection nozzle is a 3 mm diameter hole (standard).

Integral Check Valve

This poppet type spring return valve has a FKM soft seal (standard).

Sampling Double Block & Bleed Valves

This design is developed to remove a sample directly from process stream at full system pressure. The customised sampling

probe extends from the pipe flange connection for correct sample removal. Sampling valves can be provided without a probe

and valves can be provided in most of the styles and options offered for the DBB ranges.
