CAPTIVE BLEED

Vent connection at the bleed valve outlet is plugged with a metallic screwed bleed plug fitted with a captive bleed screw.

ANTI BLOW OUT STEM

The stem of MD ball valves has an anti-blow out design as BS5351 specification. The pressure thrust on the stem is s upported by a washer in antifriction material (PTFE charged).

FIRE SAFE DESIGN

Ball valves have been succeeded to fire testing and are certified fire safe. Conformance to BS6755 part II, API607, EN ISO 10497, TOTAL SGM 2040 TUY SC01.

ANTI STATIC DEVICE

Electrical continuity assured between the ball, stem, body and other components. Different materials are used as conductive bridges.

SOFT SEAT

Valves specified for standard service have a seat design including a resilient material insert at the valve seat such as DEVLON, PFA, PTFE, PTFCE, PEEK.

Single piston effect (self-relieving seats)

Fluid pressure, both upstream and d ownstream, creates a resultant thrust that pushes the seat rings against the ball. Fluid pressure acting in the body cavity creates a resultant thrust that pushes the seat rings away from the ball. The single piston design permits the automatic release of any overpressure in the body cavity when the valve is in the fully open or fully closed position. Consequently, the seat rings are «self-relieving.»

Double piston effect

Fluid pressure, both upstream and down-stream as well as in the body cavity, cates a resultant thrust that pushes the seat rings towards the ball. Valves with double piston effect seat rings require a relief valve to reduce the build-up of overpressure in the body cavity.

METAL SEATED

Valves designed for abrasive service or for operations in temperatures that prohibit the use of a resilient material have seating action provided by the metalto- metal contact between the ball and the seat rings. Seating faces are hardfaced.

In standard this valve can be supplied with high coating tungsten carbide thickness up to 400 Microns.
