Product specification

Robust ball cock, block construction, made of highly chemical-resistant PTFE.

Ball is embedded in the casing bed, which has the same shape as the ball.

Ball and stem are manufactured in one piece, therefore double bearing of the ball in the casing bed on the one hand and in the packing gland on the other hand, thus minimizing the risk of leakage.

Connections: seamless cylindrical G-internal thread. The threaded sleeves are reinforced by stainless steel rings.

Sealing of the ball by PTFE sealing sleeves, which also serve for adjustment.

Highest media resistance guaranteed by housing and sealing sleeves made of PTFE.

Technical specification

Material:

Housing: PTFE (polytetrafluoroethylene)

Sealing sleeves: PTFE (polytetrafluoroethylene)

O-ring: FPM (fluorinated rubber)

General Information

THOMAFLUID®-ball cocks with rotary handle are available in numerous variations.

Two types are available: the block construction EMP-A6 (parts 28888) on the one hand, and the compact cocks EMP-L6 on the other hand (parts 304881).

The type EMP-L6 is produced cost-effectively by injection moulding, providing a remarkable manageability and compactness of the cock body.

The block construction EMP-A6 is produced in the metal-cutting manufacturing process. The cocks are excellently suitable for direct wall mounting due to their rectangular construction. The product range varies from two-way cocks with through bore to five-way cocks with ball angled bore.

Therefore, the desired solutions can be found for specific applications:

Three-way ball cock (ball with L-bore/vertical design)

Three-way ball cock (ball with L-bore/horizontal design)

Three-way ball cock (ball with T-bore/horizontal design)

Four-way ball cock (ball with double L-bore)

Five-way ball cock (ball with angled bore, vertical)

The ball cocks are designed for max. 10 bar (at +20 °C).

Safe and reliable isolation, mixture as well as distribution of gases and liquids

High flow rates even at heavily contaminated media

Ball and stem are manufactured in one piece

Sealing sleeves made of PTFE with highest resistance to chemically aggressive media

Securing of the sealing sleeves by O-rings made of FPM

Sealing of the ball upward by stem sealing using an O-ring

Numerous connection possibilities due to compatibility with THOMAFLUID®-and MULTIFIT®-tubing connectors, pipe connectors and fittings

Easily revolving manual rotary handle with position indicator

Fastening possibilities due to fixing clamps and angle brackets

Seamless cylindrical G 1/2" and G 1/4" internal thread according to DIN ISO 228

FPM (Fluorinated rubber)

FPM is a polymer of highest quality made of fluorinated hydrocarbons (fluorine content 64 % to 70 %) and belongs to the group of elastomers

FPM has the best resistance to swelling in mineral oils compared to all elastomers

Lowest evaporation rates at high vacuum

Low permeability to gas

Outstanding radiation resistance

Excellent chemical and physical properties, almost identical to those of PTFE. The essential difference compared to PTFE is the lower cold flow, lower diffusion and better transparency.

High chemical resistance to many chemicals, ozone, heat and weather.

Unstable to polar solvents such as ketones and esters (considerable swelling), organic acids (acetic acid or formic acid), strong bases such as amines (chemical attack).

Not suitable for applications at temperatures below -20 °C as well as in hot steam.
